Susceptible Detection of Organic Molecules Based on C3B/Graphene and C3N/Graphene van der Waals Heterojunction Gas Sensors.

Constructing van der Waals (vdW) heterostructures is a prospective approach that is essential for developing a new generation of functional two-dimensional (2D) materials and designing new conceptual nanodevices. Using density-functional theory combined with a nonequilibrium Green's function approach allows for the theoretical and systematic exploration of the electronic structure, transport properties, and sensitivity of organic small molecules adsorbed on 2D C3B/graphene (Gra) and C3N/Gra vdW heterojunctions. Calculations show the metallic properties of C3B/Gra and C3N/Gra after the formation of heterojunctions. Interestingly, the heterojunctions C3B/Gra (C3N/Gra) for the adsorption of small organic molecules (C2H2, C2H4, CH3OH, CH4, and HCHO) at the C3B (C3N) side are sensitive to the chemisorption of C2H2 and C2H4. Similarly, the Gra/C3B is chemisorbed for both C2H2 and C2H4 when adsorbed on Gra side, while it is only chemisorbed for C2H2 in Gra/C3N. Interestingly, all heterojunctions on different sides are physisorbed for CH3OH, CH4, and HCHO. Furthermore, the calculated I-V curves demonstrate that the devices based on the adsorption of C2H2 and C2H4 at each side of the heterojunction have remarkable anisotropy, in with the current being considerably greater in the zigzag direction than in the armchair direction. More specifically, with C2H2 adsorbed on the Gra side, the sensitivity along the armchair direction is up to 85.0% for Gra/C3B and close to 100% for Gra/C3N. This study reveals that C3B/Gra (C3N/Gra) heterojunctions with high selectivity, high anisotropy, and excellent sensitivity are highly prospective 2D materials for applications, which further contributes new insights into the development of future electronic nanodevices.

Superhydrophilic Surface Creation and Its Temporal Transition to Hydrophobicity on Copper via Femtosecond Laser Texturing

We analyzed a process to fabricate a superhydrophilic surface on copper by forming various laser-induced periodic surface structures (LIPSS) using a Ti/sapphire femtosecond laser. For these structured surfaces, the correlation between the surface structure and the wetting characteristics was analyzed by scanning electron microscopy, atomic force microscopy, and contact angle (CA) measurement. X-ray photoelectron spectroscopy (XPS) was also employed to analyze variation of the elemental composition of the surfaces. The laser treatment produced micro/nanostructures composed of ripples whose length and width are in microscale and nanoscale, respectively. At specific conditions, the CA of a water droplet was reduced to less than 1°. The superhydrophilcity is attributed to the effect of nanoholes and nanoclusters, which consist of copper (II) oxide and copper hydroxide, having a hydrophilic effect on LIPSS. However, the pristine superhydrophilic surface spontaneously became hydrophobic after being exposed to air at room temperature for about 10 days. According to XPS analysis, the surface’s transition to hydrophobic is attributed not only to the decomposition of Cu(OH)2 but also to the adsorption of oxygen molecules and/or airborne organic molecules containing carbon, which further influences the wettability.

Stabilization effect of nano-SiO2@iron-phosphorus on ferrallisols, calcareous soil and organic soil heavily polluted by heavy metals: A fast reaction curing stabilization process

The remediation of soil pollution by heavy metals (HMs) presents a significant challenge in environmental restoration. Stabilization remediation technology has proven effective in treating HMs contaminated soil. However, its development is constrained by drawbacks such as slow reaction kinetics and low adsorption capacity. This research synthesized a nano-SiO2@iron‑phosphorus (FPOH) material by SiO32− encapsulating the iron-phosphate precipitate obtained from Fe ion and phosphate. In addition, this research applied this material to ferrallisols, calcareous soils and organic soils with three different levels of high pollution by Cd, Pb, Cu and Zn. The experimental results indicate that all experimental soils stabilized rapidly within 1 day and met the requirements of remediation engineering standards (ChinaMEE HJ 1282-2023). Analysis of the possible mechanisms suggests that the FPOH material effectively fills voids with phosphate mineral formation, preventing the secondary release of HMs. During the stabilization process, FPOH involves the adsorption of free ions and small organic molecules in the soil, which does not affect its high reactivity. The development and utilization of FPOH offer valuable insights for soil stabilization remediation.

Boosting electrochemical performance of single-walled carbon nanotube three-dimensional architectures through appropriate selection of organic dispersant

The choice of organic dispersant in the fabrication of 3D carbon nanotube architectures affects their macroscopic properties. Binder-free papers (referred to as buckypapers, BPs) consisting of single-walled nanotubes (SWCNTs) fabricated by vacuum filtration of nanotube suspensions in isopropanol, ethanol, benzoic acid dissolved in ethanol and lemon oil show a work of adhesion of water that varies from 25.7 to 112.2 mJ·m−2. Bulk electrical resistivity also changes significantly from 145 to 1010 mΩ cm. Raman and FTIR spectra of pristine SWCNTs and BPs show evidence of permanent adsorption of organic molecules on SWCNTs. Heterogeneous electron transfer (HET) standard rate constants, k0, for ferro/ferricyanide and hexaammineruthenium(II)/(III) redox probes estimated from cyclic voltammetry measurements on BP electrodes vary from 12.6×10−4cms−1 to 32.7×10−4cms−1 and 12.8×10−4cms−1 to 26.0×10−4cms−1, respectively, depending on the dispersant used. Calculations using the Gerischer-Marcus model show that molecules adsorbed act as electron donors that boost HET kinetics and cause a shift in the reaction half-wave potential. The level of doping of nanotubes depends on the dipole moment of the dispersant molecules and proton affinity. Thus, the electrocatalytic activity of three-dimensional architectures composed of nanotubes can be adjusted by selecting an appropriate dispersant.

Superhydrophobic performance of aluminum textured with a picosecond laser

Aluminum is a common and light engineering metal with high strength, good processability, corrosion resistance, high electrical conductivity, and strong recyclability, properties that allow its wide use in different fields. Strengthening the surface properties of aluminum materials can not only enable aluminum materials to be applied to complex environments but also extend their service life. In this study, two kinds of micro–nano structures—unidirectional micro-grooves and grid micro-grooves—were prepared on the surface of 1060 aluminum using picosecond-laser direct etching, so that its surface can attain superhydrophobic properties and enhance its application performance. The effect of the scanning interval of picosecond laser on the hydrophobic performance was investigated, and the findings indicate that the hydrophobic properties are most effective by using scanning interval of 20 μm. The scanning electron microscope (SEM) and atomic force microscope (AFM) analyses revealed the formation of a micro-nano structure resembling nanoflower particles on the laser-treated aluminum surface, which contributed to increased surface roughness. EDS analysis indicated an increase in carbon (C) content, likely due to the adsorption of organic molecules from the air, which further promoted hydrophobicity. X-ray diffraction spectrometry (XRD) and X-ray photoelectron spectroscopy (XPS) provided insights into the surface chemistry and the presence of various elements and compounds. The superhydrophobic aluminum surfaces demonstrated remarkable stability and self-cleaning capabilities, desirable traits for many practical applications. This study provides a simple and rapid method for preparing superhydrophobic materials on aluminum surfaces and has potential practical application value.This innovation paves the way for the development of high-performance aluminum materials suitable for a wide range of environments and uses.

Enhancement of Magnetic Stability in Antiferromagnetic CoO Films by Adsorption of Organic Molecules.

Antiferromagnets are a class of magnetic materials of great interest in spintronic devices because of their stability and ultrafast dynamics. When interfaced with an organic molecular layer, antiferromagnetic (AF) films are expected to form a spinterface that can allow fine control of specific AF properties. In this paper, we investigate spinterface effects on CoO, an AF oxide. To access the magnetic state of the antiferromagnet, we couple it to a ferromagnetic Co film via an exchange bias (EB) effect. In this way, the formation of a spinterface is detected through changes induced on the CoO/Co EB system. We demonstrate that C60 and Gaq3 adsorption on CoO shifts its blocking temperature; in turn, an increase in both the EB fields and the coercivities is observed on the EB-coupled Co layer. Ab initio calculations for the CoO/C60 interface indicate that the molecular adsorption is responsible for a charge redistribution on the CoO layer that alters the occupation of the d orbitals of Co atoms and, to a smaller extent, the p orbitals of oxygen. As a result, the AF coupling between Co atoms in the CoO is enhanced. Considering the granular nature of CoO, a larger AF stability upon molecular adsorption is then associated with a larger number of AF grains that are stable upon reversal of the Co layer.

Steering benzyl alcohol electrooxidation coupled with hydrogen evolution via hetero‐interface construction

AbstractIt is still a challenge to develop electrocatalyst for the efficient adsorption and conversion of organic molecule in aqueous media. Herein, a hetero‐interface structure based on CuO@Ni(OH)2 is rationally designed to enhance the performance of benzyl alcohol oxidation to benzoic acid. A high Faradaic efficiency of 99% and the yield of 3.09 mmol cm−2 h−1 are achieved at 1.70 V versus reversible hydrogen electrode, outperforming the previously reported electrocatalysts. Furthermore, a membrane‐free flow electrolyzer was assembled based on CuO@Ni(OH)2 hetero‐interface, exhibiting a much high yielding of benzoic acid (6.73 mmol cm−2 h−1) and hydrogen (0.35 L cm−2 h−1) with excellent stability. Both experimental data and density functional theory calculations verify that the electron is tend to accumulate at the hetero‐interface, thus accelerating the adsorption of reactant and intermediate and reducing the energy barrier of the conversion of benzyl alcohol to benzoic acid.

Understanding selective hydrogenation of phenylacetylene on PdAg single atom alloy: DFT insights on molecule size and surface ensemble effects

Single atom alloys (SAAs) have proven to be effective catalysts, offering customizable properties for diverse chemical processes. Various metal combinations are used in SAAs and Pd dispersed materials are frequently employed in catalyzing hydrogenation reactions. Herein, we explore the hydrogenation of phenylacetylene to styrene and ethylbenzene on PdAg SAA using density functional theory calculations. Our results show that while PdAg SAA does improve the activity of the host Ag towards hydrogenation, a dilute PdAg SAA surface with isolated Pd-atoms is not selective towards partial hydrogenation of phenylacetylene. Additionally, we investigate how the size of the reactant molecule, the size of the metal alloy ensemble, and the ligand effect impact the hydrogenation process. The SAA enhances the binding strengths of various organic adsorbates, although this effect diminishes as the adsorbate size increases. Our findings indicate the dilute PdAg exhibits selectivity towards hydrogenation of smaller molecules such acetylene due to its distinct adsorption geometry. The selective hydrogenation of phenylacetylene necessitates a surface Pd dimer ensemble. Our research highlights the importance of both reactant molecule size and surface configurations in SAA catalysts. This is particularly crucial when dealing with the adsorption of sizable organic molecules where the functional group can adopt different adsorption modes.

Electronic behavior of organic molecules adsorbed on monolayer SiC

Studying the adsorption of organic molecules is a good approach for exploring the electronic conducts of two-dimensional (2D) materials. We utilized density functional theory (DFT) to research the structure and electronic behaviors of organic molecules (Tetracyanoquinodimethane(TCNQ), Tetracyanoethylene(TCNE), Tetrathiafulvalene (TTF)) in the SiC adsorption system. After organic molecules are adsorbed on monolayer SiC, the charge difference density (CDD) and the plane average CDD indicate the presence of charge transfer between monolayer SiC and organic molecules. The research results indicate that the impurity energy level appears in the band structure and is contributed by organic molecules. Facts prove that the TCNQ, TCNE, and TTF molecules may inject additional carriers into the SiC layer. TCNQ and TCNE molecules are the electron acceptors, while TTF molecule is the electron donor. The p-type doping and n-type doping were achieved in monolayer SiC, and induce effective p-type doping behavior. Because TCNQ, TCNE, and TTF molecules inject additional holes or electrons into the monolayer SiC, the dimension of the work function can be regulated, expanding the field emission capability range of SiC-based electronic devices. The current-voltage (I-V) curves reveal that after organic molecules adsorbed on monolayer SiC, the transport current capability of the n-type doping system is stronger than the p-type doping system. Therefore, SiC system electrical characteristics may be regulated by organic molecule adsorption. Our work provides a theoretical foundation for SiC application in nano electronic device.

The Inhibition Action of Some Brij-Type Nonionic Surfactants on the Corrosion of OLC 45 in Various Aggressive Environments.

The corrosion protection property of three Brij-type surfactants, namely, Brij 35, Brij 56 and Brij 58P, was considered on OLC 45 carbon steel in a 0.5 M H2SO4 medium. The efficacy for these organic compounds was examined using potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) methods, scanning electron microscopy (SEM) procedures, and Fourier transform infrared (FT-IR) spectroscopy. We hypothesized that these surfactants hinder the corrosion for OLC 45 samples through a protecting mechanism owing to the adsorption of organic molecules that form an inhibitive film or through the formation of complex oxides. These surfactants exhibited an appreciable protective effect against OLC 45 corrosion, operating as mixed inhibitors, as could be demonstrated by their influence on the electrochemical characteristics of the metallic substrates. The adsorption of surfactants over the substrates zone conformed to the representation of the Langmuir isotherm. The effect of temperature on the electrochemical comportment of the OLC 45 specimens in H2SO4 without and with Brij at 800 ppm was examined in the temperature interval of 293 to 333 K. The negative estimate of thermodynamic attributed as Gibbs free energy of adsorption presented the spontaneity of the adsorption activity. The investigation with FT-IR and SEM established the adsorption of Brij and the constitution of the corrosive components on the OLC 45 surface. Electrochemical determinations of these surfactants indicated its anticorrosion inhibition performance and the highest inhibition of 96% was reached when the Brij 35 concentration was at 800 or 1000 ppm, while for Brij 56 and Brij 58P, the highest inhibition was obtained when their concentrations were 500, 800, or 1000 ppm.

Realization of either physisorption or chemisorption of 2H-tetraphenylporphyrin on the Cu(111) from density functional theory

The adsorption of organic molecules to surfaces is a central issue to achieve fully-functional molecular devices, for which porphyrins are well-studied due to their chemical stability and functional diversity. Herein, we investigate both the physical and the chemical adsorption of the free-base tetraphenylporphyrin 2H-TPP on the Cu(111) surface within the framework of density functional theory and find that the most stable physisorbed configuration is more weakly bound by −0.31 eV than the chemisorbed configuration. We use the electron localization function to investigate the difference in binding mechanisms between strong physisorption and weak chemisorption. We have computed a reaction barrier of 0.12 eV in going from physical binding to chemical bonding to the surface, and a barrier of 50 meV in going between neighboring physical binding sites. Our results support the possibility of realizing free-base porphyrins either physisorbed or chemisorbed on Cu(111) depending on the deposition procedure and experimental conditions.

Construction of Ag─Co(OH)2 Tandem Heterogeneous Electrocatalyst Induced Aldehyde Oxidation and the Co-Activation of Reactants for Biomass Effective and Multi-Selective Upgrading.

The electrocatalytic oxidation of 5-hydroxymethylfurfural (HMF) provides a feasible way for utilization of biomass resources. However, how to regulate the selective synthesis of multiple value-added products is still a great challenge. The cobalt-based compound is a promising catalyst due to its direct and indirect oxidation properties, but its weak adsorption capacity restricts its further development. Herein, by constructing Ag─Co(OH)2 heterogeneous catalyst, the efficient and selective synthesis of 5-hydroxymethyl-2-furanoic acid (HMFCA) and 2,5-furan dicarboxylic acid (FDCA) at different potential ranges are realized. Based on various physical characterizations, electrochemical measurements, and density functional theory calculations, it is proved that the addition of Ag can effectively promote the oxidation of aldehyde group to a carboxyl group, and then generate HMFCA at low potential. Moreover, the introduction of Ag can activate cobalt-based compounds, thus strengthening the adsorption of organic molecules and OH- species, and promoting the formation of FDCA. This work achieves the selective synthesis of two value-added chemicals by one tandem catalyst and deeply analyzes the adsorption enhancement mechanism of the catalyst, which provides a powerful guidance for the development of efficient heterogeneous catalysts.

Activation of iron oxide minerals in an aquifer by humic acid to promote adsorption of organic molecules

In aquifers, the sequestration and transformation of organic carbon are closely associated with soil iron oxides and can facilitate the release of iron ions from iron oxide minerals. There is a strong interaction between dissolved organic matter (DOM) and iron oxide minerals in aquifers, but the extent to which iron is activated by DOM exposure to active iron minerals in natural aquifers, the microscopic distribution of minerals on the surface, and the mechanisms involved in DOM molecular transformation are currently unclear. This study investigated the nonbiological reduction transformation and coupled adsorption of iron oxide minerals in aquifers containing DOM from both macro- and micro perspectives. The results of macroscopic dynamics experiments indicate that DOM can mediate soluble iron release during the reduction of iron oxide minerals, that pH strongly affects DOM removal, and that DOM is more efficiently degraded at low rather than high pH values, suggesting that a low pH is conducive to DOM adsorption and oxidation. Spherical aberration-corrected scanning transmission electron microscopy (SACTS) indicates that the reacted mineral surfaces are covered with large amounts of carbon and that dynamic agglomeration of iron, carbon, and oxygen occurs. At the nanoscale, three forms of DOM are found in the mineral surface agglomerates (on the surfaces, inside the surface agglomerates, and in the polymer pores). The microscopic organic carbon and iron mineral reaction patterns can form through oxidation reactions and selective adsorption effects. Fourier transform ion cyclotron resonance mass spectra indicate that both synergistic and antagonistic reactions occur between DOM and the minerals, that the release of iron is accompanied by DOM decomposition and humification, that large oxygen- and carbon-containing molecules are broken down into smaller oxygen- and carbon-containing compounds and that more molecules are produced through oxidation under acidic rather than alkaline conditions. These molecules provide adsorption sites for sediment, meaning that more iron can be released. Microscopic evidence for the release of iron was acquired. These results improve the understanding of the geochemical processes affecting iron in groundwater, the nonbiological transformation mechanisms that occur at the interfaces between natural iron minerals and organic matter, groundwater pollution control, and the environmental behavior of pollutants.

New Progress on London Dispersive Energy, Polar Surface Interactions, and Lewis's Acid-Base Properties of Solid Surfaces.

The determination of the polar surface free energy, polar properties, and Lewis's acid base of solid materials is of capital importance in many industrial processes, such as adhesion, coatings, two-dimensional films, and adsorption phenomena. (1) Background: The physicochemical properties of many solid particles were characterized during the last forty years by using the retention time of injected well-known molecules into chromatographic columns containing the solid substrates to be characterized. The obtained net retention time of the solvents adsorbed on the solid, allowing the determination of the net retention volume directly correlated to the specific surface variables, dispersive, polar, and acid-base properties. (2) Methods: Many chromatographic methods were used to quantify the values of the different specific surface variables of the solids. However, one found a large deviation between the different results. In this paper, one proposed a new method based on the London dispersion equation that allowed the quantification of the polar free energy of adsorption, as well as the Lewis's acid-base constants of many solid surfaces. (3) Results: The newly applied method allowed us to obtain the polar enthalpy and entropy of adsorption of polar model organic molecules on several solid substrates, such as silica, alumina, MgO, ZnO, Zn, TiO2, and carbon fibers. (4) Conclusions: our new method based on the separation between the dispersive and polar free surface energy allowed us to better characterize the solid materials.

First-principles investigation on molecular adsorption on 2D perovskite toward optoelectronic application

Halide perovskite materials have received attention for optoelectronic applications, and it is promising to further engineer the perovskite systems via surface molecular adsorption to improve optoelectronic properties. In this study, we comprehensively investigate atomic structures and properties of surface molecule-modified low-dimensional halide perovskite systems represented by Cs2PbBr4 via first-principles calculations. The calculation pinpoints the effectiveness of molecular adsorption to fine tune the structural and electronic properties of low-dimensional halide perovskite material, which can be stabilized via interfacial secondary bonds such as anion···π, halogen bond and hydrogen bond interactions. Noteworthily, the anion···π interaction is almost ubiquitous in the aromatic molecule/perovskite systems in the present study assuming the adsorption mode is horizontal, signifying the versatility of anion···π interaction to functionalize low-dimensional halide perovskite surfaces. In addition, the amine-containing molecules tend to initiate molecule → perovskite interfacial charge transfer direction upon light excitation while most other organic molecules favors halogen → lead electron transfer process inside the perovskite substrate. Importantly, the polaron calculations suggest the possibility of forming large polarons to protect charge transport via effective electron- and hole-phonon coupling upon molecular adsorption. This study highlights the effectiveness of organic molecule adsorption to fine tune optoelectronic properties of low-dimensional perovskite systems via the formation of interfacial secondary bonds.

Heats of Adsorption in Molecules

The number of chemical reactions proceed by the phenomenon of adsorption of organic molecules the heat is liberated which is called the heat of adsorption and this can be calculated by using the mathematical chemistry and gauss Bonett Theory differential geometry. When the molecules is absorbed on the interacting surfaces of organic molecules the phenomenon is called adsorptionThe physico-chemical properties of organic molecules depends on the nature of catalytic surfaces of organic molecules. The importance of this methods used in the study of bio-chemical reaction and catalytic reaction proceed on the surfaces of organic molecules.

Adsorption behaviors of organic molecules on Nb/Zr–modified bismuthene: A first–principles study

In this work, the geometric and electronic properties of the adsorption of volatile organic molecules (VOCs) such as CH2O, C2H4O, C2H6O on bismuthene monolayer with transition metal (TM = Nb, Zr) atoms adsorbed are investigated by using first–principles methods, aiming to explore the potential applications of TM–modified bismuthene monolayer in the field of organic molecular gas sensors. In contrast to the adsorption of organic molecules on Zr–bismuthene, Nb–bismuthene appears the chemisorption with multiple organic molecules, and it can be found that Nb–bismuthene could stably adsorb target molecules and exhibit outstanding charge transfer. The longer desorption time of organic molecules on Nb–bismuthene and the higher organic molecular adsorption capacity of the substrate at most temperatures, which suggests that Nb–bismuthene is suitable as a disposable sorbent for organic molecules, providing a viable direction for the application of Nb–bismuthene monolayer as a sensitive material for the removal of organic molecules.

Heterogeneous interface induced Co3O4-NiO catalyst for efficient electrocatalytic 5-Hydroxymethylfurfural oxidation

The electrooxidation of 5-hydroxymethylfurfural (HMF) provides an efficient and environmentally friendly approach to obtain high-value chemicals from biomass. In this study, porous nanocube framed Co3O4-NiO electrocatalysts with heterogeneous interface are constructed for efficient HMF oxidation reaction (HMFOR). The heterogeneous interface modulates the electronic properties of Co and Ni atoms, enhances the oxidation state of Ni species, which is favorable for the oxidation of HMF. Compared to pure Co3O4 and NiO, Co3O4-NiO exhibits a lower onset potential (1.22 V vs. RHE), higher FDCA yield (83.33 %) and Faraday efficiency (89.47 %). Furthermore, the results of open circuit potential (OCP), high-performance liquid chromatography (HPLC) product analysis and in-situ electrochemical impedance spectroscopy (EIS) demonstrate that the Co3O4-NiO heterogeneous interface effectively enhances the adsorption and transformation of organic molecules and OH– species, and facilitates the further oxidation of 5-formyl-2-furancarboxylic acid (FFCA) to 2,5-furandicarboxylic acid (FDCA), thus improving the performance of HMFOR. This work illustrates the effect of heterogeneous interface on Co3O4-NiO catalyst for HMFOR and provides a direction for the development of high-performance electrocatalysts for HMFOR.

Carbenes trapping on Aluminum-Magnesium surface implanted with Silicon, Germanium, Tin: Promising of semiconductors by molecular modeling approach

Al-Mg surface doped silicon, germanium and tin is theoretically studied using first-principles density functional theory (DFT) at the CAM-B3LYP/EPR-III, LANL2DZ,6-31+G(d,p) level of theory to explore the chemical adsorption and corrosion inhibition of organic carbenes through coating process. The fluctuation of NQR is estimated the inhibiting role of pyridine and its derivatives (picoline, 3-picoline,4-picoline,2,4-lutidine) for (Si, Ge, Sn)-doped Al-Mg alloy nanosheet due to concerning nitrogen in the benzene ring of related heterocyclic compounds becoming close to the monolayer nanosurface of Al-Mg-X (X = Si, Ge, Sn) nanoalloys. The NMR spectroscopy remarks that (Si, Ge, Sn)-doped Al-Mg alloy nanosheet has maximum band wavelengths approximately between 10 ppm–2000 ppm accompanying the sharpest peaks for inhibitors → Al-Mg-X which are between 10 ppm–100 ppm. IR spectroscopy has exhibited that (Si, Ge, Sn)-doped Al-Mg alloy nanosheet with the fluctuation in the frequency of intra-atomic interaction leads us to the most influence in the vicinage atoms generated due to inter-atomic interaction. The maximum IR spectrum for complexes of [inhibitor → Al-Mg-X (X = Si, Ge, Sn)] is observed in the frequency range between 500 cm−1–3500 cm−1. This work exhibits that proper monitoring of the coating mechanism by Langmuir adsorption can illustrate inhibiting the aluminum nanoalloys corrosion through an investigation of their structural and thermodynamic properties. This work investigates the characteristics, band structure, and projected density of state (PDOS) of Al-Mg nanoalloy doped with Si, Ge, Sn elements for increasing the corrosion inhibition of the surface through adsorption of organic molecules of carbenes in the surface coatings process. This article can be helpful in a range of applications which uses Al-Mg alloy for the study of energy storage and adsorption of air pollution or water contamination. Many different approaches such as surface coatings, alloying and doping can be adopted to protect the surface.
