Bi2O3 microspheres combined electron-deficient B-reduced graphene oxide as functional electrocatalyst for effective synthesis urea from N2 and CO2

Electrochemical synthesis urea, which couples N2 and CO2, is seen as a potential promising and sustainable alternative to traditional harsh industrial process. However, the significance of the rational design electrocatalyst has been enthused due to the hard activation of N≡N, the prevalence of sub-reactions, and the low current density. Herein, an electrocatalyst, Bi2O3/B-reduced graphene oxide (RGO) was prepared for synthesis urea with a Faraday efficiency (FE) of 12.8 %, urea yield of 9.2 mmol g−1h−1 and urea current density 0.47 mA cm−2 at −0.8 V, while maintaining long-term stability. The Bi2O3/B-RGO possess a unique porous structure with continuous micron pores that facilitated the rapid mass transfer, improved kinetic efficiency and enlarged electroactive sites, which together improve the urea synthesis performance. Interestingly, the Bi2O3/B-RGO electrocatalyst is not only have excellent electrochemical properties, but also favours the adsorption and activation of reactants (N2 and CO2) due to the B-RGO (Lewis acid) and the Bi2O3 (Lewis base). This work may provide new insights into the exploration of advanced catalysts for electrochemical urea synthesis and other sustainable applications.

Enhanced Li storage of pure crystalline-C60 and TiNb2O7-nanostructure composite for Li-ion battery anodes

We propose a method for producing composite materials (hTNO@C60) comprising crystalline C60 particles and hollow-structured TiNb2O7 (hTNO) nanofibers via facile liquid–liquid interface precipitation followed by low-temperature annealing. This allows the systematic design of crystalline C60 as an active material for Li-ion battery anodes. The hTNO@C60 composite demonstrates outstanding cyclic stability, retaining a capacity of 465 mA h g−1 after 1,000 cycles at 1 A g−1. It maintains a capacity of 98 mA h g−1 even after 16,000 ultralong cycles at 8 A g−1. The enhancement in electrochemical properties is attributed to the successful growth and uniform doping of crystalline C60, resulting in improved electrical conductivity. The excellent electrochemical stability and properties of these composites make them promising anode materials.

Polypyride intercalation boosting the kinetics and stability of V3O7·H2O cathodes for aqueous zinc-ion batteries

V3O7·H2O (VO) is a high capacity cathode material in the field of aqueous zinc ion batteries (AZIBs), but it is limited by slow ion migration and low electrical conductivity. In this paper, polypyridine (PPyd) intercalated VO with nanoribbon structure was prepared by a simple in-situ pre-intercalation, which is noted VO-PPyd. The total density of states (TDOS) shows that after the pre-intercalation of PPyd, an intermediate energy level appears between the valence band and conduction band, which provides a step that can effectively reduce the band gap and enhance the electron conductivity. Furthermore, the density functional theory (DFT) results found that Zn2+ is more easily de-intercalated from the V-O skeleton, which proves that the embeddedness of PPyd improves the diffusion kinetics of Zn2+. Electrochemical studies have shown that VO-PPyd cathode materials exhibit excellent rate performance (high specific capacity of 465 and 192 mA h g−1 at 0.2 and 10 A g−1, respectively) and long-term cycling performance (92.7% capacity retention rate after 5300 cycles), due to their advantages in structure and composition. More importantly, the energy density of VO-PPyd//Zn at 581 and 5806 W kg−1 is 375 and 247 W h kg−1, respectively. VO-PPyd exhibits excellent electrochemical properties compared to previously reported vanadium based cathodes, which makes it highly competitive in the field of high-performance cathode materials of AZIBs.

Sustainable Balsa wood-derived high-rate hard carbon anodes for sodium-ion hybrid capacitors

Biomass-derived hard carbons have broad prospects toward commercialized sodium-ion batteries because of their advantages of low cost, renewability, and the diversity of precursors. Although hard carbon materials have advantages such as considerable specific capacity and good stability, the application of hard carbon materials in sodium-ion hybrid capacitors (SIHCs) is still limited by their low-rate capability. In this work, a direct carbonization method is used to prepare hard carbons derived from Balsa woods (BHCs). The best rate capability of BHCs is obtained by an optimized carbonization temperature of 1400 °C. The prepared hard carbon shows a smaller closed pore size (1.77 nm) compared to most recently reported hard carbons, which ensures their high rate capability. At the carbonization temperature of 1400 °C, BHC achieves the highest capacity of 296 mAh g−1. BHC-1400 also exhibits a high capacity retention of 54.9 % at a current density of 5 A g−1. The excellent electrochemical properties indicate that the BHCs have potential in the application of high-rate SIHCs.

Biomass derived hard carbon materials for sodium ion battery anodes: Exploring the influence of carbon source on structure and sodium storage performance

Compared to the scarce resources of lithium-ion batteries, sodium ion batteries have gradually become an ideal carrier for large-scale energy storage systems due to their abundant raw material resources. In recent years, hard carbon as an anode material for sodium ion batteries has attracted much attention. Biomass materials have become an ideal hard carbon precursor due to their natural and renewable advantages. This article evaluates the effect of hard carbon derived from three types of biomass waste (peanut shell, coffee grounds, and sugarcane bagasse) on the electrochemical performance of sodium ion batteries through pre carbonization pyrolysis method. The three materials exhibit different structures and surface functional group contents. Compared with coffee grounds and sugarcane bagasse, peanut shell-derived hard carbon has lower structural ordering and smaller specific surface area, and exhibits a higher initial Coulombic efficiency of 53.84 %. The initial reversible capacity of the HC-P electrode is 203.6 mAh/g, and the Coulombic efficiency of the electrode is close to 100 % with a reversible capacity of 127.1 mAh/g and a capacity retention of 81.4 % after cycling 100 at 1C current. The excellent electrochemical properties of HC-P can be attributed to its higher C=O bond content, larger layer spacing and lamellar structure.

The NSP-Gr-1 catalyst shows the high onset potential (1.035 V), half-wave potential (0.79 V) and limiting current density (−5.33 mA cm−2) for ORR. The power density of the zinc-air battery assembled with the NSP-Gr-1 catalyst achieves 163.1 mW cm−2 at 186.7 mA cm−2, which is much higher than the maximum power density of 140.0 mW cm−2 at 190 mA cm−2 for commercial Pt/C. The discharge stability under different current densities is outstanding.

Nitro-groups containing compounds are widely used in various applications but are considered highly toxic compounds. 4-nitrotoluene (4NT) belongs to the nitro-aromatic compounds and is a highly hazardous water contaminant. Thus, exploring new materials with excellent physiochemical and electrochemical properties is desirable for the construction of efficient 4NT sensors. The present study reports the fabrication of manganese dioxide/sulfur-doped reduced graphene oxide (α-MnO2/S@rGO) via hydrothermal synthesis procedure. The well-characterized α-MnO2/S@rGO was employed as a catalyst for the construction of α-MnO2/S@rGO modified screen printed carbon electrode (SPCE) for the detection of 4NT using cyclic voltammetry (CV). The α-MnO2/S@rGO modified electrode exhibits good electro-catalytic properties for the detection of 4NT compared to the bare SPCE, α-MnO2-, or S@rGO-modified electrodes. A reasonable detection limit of 0.5 μM with sensitivity of 1.97 μA.μM−1.cm−2 was obtained using α-MnO2/S@rGO modified electrode. The α-MnO2/S@rGO modified electrode demonstrated considerable selectivity for the sensing of 4NT in presence of various electro-active species. Note that the combination of catalytic α-MnO2 and conductive S@rGO present excellent synergistic interactions which improved the performance of the α-MnO2/S@rGO-modified electrode.

Boron and nitrogen co-doped sodium alginate-based porous carbons for durable and fast Zn-ion hybrid capacitors

In recent years, zinc-ion hybrid capacitors (ZIHCs) have attracted increasing attention due to their environmental friendliness and excellent electrochemical properties. However, their performance is mainly limited by the electrochemical performance of the cathode, so it is necessary to develop an advanced cathode material. N, B co-doped sodium alginate-based porous carbon (NBSPC) was prepared by one-step co-carbonization using sodium alginate as the matrix and NH4B5O8 as the N and B source. This N, B co-doping strategy improves the pore structure of the carbon materials and increases the number of surface functional groups, greatly improving the capacitive behavior of the raw materials and thus improving their electrochemical performance. When used as the cathode in ZIHCs, the NBSPC had an excellent rate performance (85.4 mAh g−1 even at ultra-high current density of 40 A g−1) and good cycling stability (15 000 cycles at 20 A g−1 with a capacity retention rate of 94.5%).

As negative materials in Li–ion batteries, the Co3O4 active material exhibits high charge/discharge specific capacity, good rate performance and satisfactory cycle stability. The excellent electrochemical properties are inevitably related to the structural characteristics of the electrode material itself, including regular morphology, rich pore structure, large specific surface area, high crystallinity, nanoscale particle size, etc.

FeNP@MIL-101(Fe)-Based Carbon Nanotube Composite for Energy Storage Applications.

Metal-organic frameworks (MOFs) are of great interest for energy applications due to their high porosity, high charge storage capacity, and large number of active redox sites. It is important to enhance the performance of metal-organic frameworks through modification in order to increase their potential applications. Unique Fe nanoparticle (NP) in the Materials of Institute Lavoisier (MIL) series embedded in the carbon nanotube (CNT), FeNP@MIL-101(Fe)/CNT-based, nanocomposites have been synthesized using suitable hierarchical micromesoporous structures. These were fabricated by simple and straightforward solvothermal methods, and their electrochemical charge storage performance was investigated. The energy storage application using the FeNP@MIL -101(Fe)/CNT composite as a supercapacitor electrode was implemented for the first time. Various techniques were used to characterize this composite. It has excellent electrochemical properties when used as electrode material in 1 M KOH solution, including a high capacitance of up to 1305 F g-1 at 1 A g-1 and a long cycling stability of 95.7% capacitance retention after 10,000 cycles. Moreover, symmetric two-electrode electrochemical experiments showed that the composite achieved an energy density of 98.65 Wh kg-1 and a power density of 9000 W kg-1, The combination of microporous and mesoporous structures, increased surface area, and higher electrical conductivity are the main reasons for the high performance. The integration of FeNP@MIL-101(Fe) with the CNT creates new ion diffusion pathways, improves the hierarchical pore properties, and exposes the FeNP@MIL-101(Fe) cluster to more redox active sites, which improves the charge storage performance.

Facile Fabrication of Large-Area CuO Flakes for Sodium-Ion Energy Storage Applications.

CuO is recognized as a promising anode material for sodium-ion batteries because of its impressive theoretical capacity of 674 mAh g-1, derived from its multiple electron transfer capabilities. However, its practical application is hindered by slow reaction kinetics and rapid capacity loss caused by side reactions during discharge/charge cycles. In this work, we introduce an innovative approach to fabricating large-area CuO and CuO@Al2O3 flakes through a combination of magnetron sputtering, thermal oxidation, and atomic layer deposition techniques. The resultant 2D CuO flakes demonstrate excellent electrochemical properties with a high initial reversible specific capacity of 487 mAh g-1 and good cycling stability, which are attributable to their unique architectures and superior structural durability. Furthermore, when these CuO flakes are coated with an ultrathin Al2O3 layer, the integration of the 2D structures with outer nanocoating leads to significantly enhanced electrochemical properties. Notably, even after 70 rate testing cycles, the CuO@Al2O3 materials maintain a high capacity of 525 mAh g-1 at a current density of 50 mA g-1. Remarkably, at a higher current density of 2000 mA g-1, these materials still achieve a capacity of 220 mAh g-1. Moreover, after 200 cycles at a current density of 200 mA g-1, a high charge capacity of 319 mAh g-1 is sustained. In addition, a full cell consisting of a CuO@Al2O3 anode and a NaNi1/3Fe1/3Mn1/3O2 cathode is investigated, showcasing remarkable cycling performance. Our findings underscore the potential of these innovative flake-like architectures as electrode materials in high-performance sodium-ion batteries, paving the way for advancements in energy storage technologies.

Construction of MOF-74 derived CuFe/C alloy highly dispersed on ultrathin single layered reduced graphene for electrochemical determination of paracetamol

Paracetamol (PAT) is a widely used drug for fever reduction and pain relief, but its accumulation due to overuse can lead to detrimental effects on human health and environment. Here, a novel composite material CuFe/C@rGO with excellent electrochemical properties was successfully constructed by loading carbon-encapsulated CuFe alloy (CuFe/C) on ultrathin single layered reduced graphene oxide (rGO) surface for PAT detection. Firstly, the CuFe/C nanoparticles was derived from MOF-74 as bimetallic ‘preassembly platform’ to obtain high dispersiveness, huge accessible surface area, and uniform pore structure of the resulted material. And then the CuFe/C was uniformly dispersed on rGO to effectively avoid the aggregation of CuFe/C and increase the conductivity of composite material. In virtue of the synergistic effect of CuFe/C and rGO, the composite material modified glassy carbon electrode CuFe/C@rGO/GCE would be endowed with abundant electrocatalytic acitive sites and fast charge transfer speed between electrode surface and analyte. Expectedly, the CuFe/C@rGO/GCE shows outstanding sensing performance with wide linear ranges of 0.006–110 μM, low detection limit of 0.0015 μM (S/N=3), together with superior reproducibility, stability and anti-interference. This developed composite material as a flexible sensing platform can be used to detect PAT in real samples with a satisfactory recovery.

Molybdenum disulfides (MoS2) is considered as promising electrode materials (E-M) for high electrochemical performance (ECP) of lithium-ion batteries and supercapacitors due to their layered nanostructures. Herein, MoS2, MgS and hetrostructure MgS/MoS2 E-Ms comprising of nano-particles/sheets/needles like structures are synthesized on Nickel foam (Ni–F) by a simple home-made chemical vapor deposition (CVD) technique. The XRD analysis confirmed the formation of MoS2, MgS and MgS/MoS2 polycrystalline E-Ms growing along different directions. The FESEM analysis is confirmed that the addition of MgS layer over the surface of MoS2 change the surafce morphology from nano-particles to nano-needles. The change in structural and microstructural features is indicated the appearance of defects, micro-strain and dislocations density which are fruitful for excellent ECP.

The simulations of Power's Law and Dunn's model is confirmed that the excellent ECP is due to both capacitive and diffusive controlled contributions of heterostructured MgS/MoS2/Ni–F E-Ms. Additionally, MgS/MoS2/Ni–F E-Ms have both battery and pseudocapacitive nature due to unique nano-needles like morphology. The excellent electrochemical properties of MgS/MoS2/Ni–F E-Ms substantiate their potential applications in portable energy storage devices.

Fabrication of Microgel-Modified Hydrogel Flexible Strain Sensors Using Electrohydrodynamic Direct Printing Method.

Hydrogel flexible strain sensors, renowned for their high stretchability, flexibility, and wearable comfort, have been employed in various applications in the field of human motion monitoring. However, the predominant method for fabricating hydrogels is the template method, which is particularly inefficient and costly for hydrogels with complex structural requirements, thereby limiting the development of flexible hydrogel electronic devices. Herein, we propose a novel method that involves using microgels to modify a hydrogel solution, printing the hydrogel ink using an electrohydrodynamic printing device, and subsequently forming the hydrogel under UV illumination. The resulting hydrogel exhibited a high tensile ratio (639.73%), high tensile strength (0.4243 MPa), and an ionic conductivity of 0.2256 S/m, along with excellent electrochemical properties. Moreover, its high linearity and sensitivity enabled the monitoring of a wide range of subtle changes in human movement. This novel approach offers a promising pathway for the development of high-performance, complexly structured hydrogel flexible sensors.

Ultrafast and selective detection of dopamine by DC sputtered highly oriented CuO thin films: Effect of electroactive interfering agents and temperature

Dopamine and serotonin are two neurotransmitters that play critical role in human physiology. In this work, it has been aimed to synthesize a chip-based sensing platform that can detect dopamine precisely in a non-enzymatic way in presence of a series of electroactive interfering agents. Copper oxide (CuO), a p-type material with excellent surface and electrochemical properties, has been deposited through direct current (DC) sputtering technique on indium doped tin oxide (ITO) coated glass substrates as the sensing platform. The structure, phase purity and other essential properties of the modified electrode were established through x-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), atomic force microscopy (AFM), Fourier transform infrared spectroscopy (FTIR) and ultraviolet – visible (UV–Vis) spectroscopy. Detailed electrochemical investigations with the modified electrode have also been carried out using cyclic voltammetry (CV), chronoamperometry (i – t) and electrochemical impedance spectroscopy (EIS) that revealed ultrafast response (10 ms), excellent sensitivity (5.41 µAµM-1cm−2) and low limit of detection (LoD) of 0.46 µM for the electrode towards dopamine. The electrode exhibited sensitivity of 0.37 µAµM-1cm−2 with average LoD of 19.2 µM towards serotonin, which is inferior to dopamine. The threshold response potential was also quite different for dopamine and serotonin. The modified electrode was also found to be nonresponsive to a series of electroactive interfering agents, making it dopamine selective. The role of p-type conductivity of the electrode material towards such selective detection of dopamine was also explained. The electrode was notably reliable from the point of view of electrochemical performance and structural stability. Real sample analysis was also carried out by taking urine sample from adult male human.

Machine-Learning-Assisted Development of Gel Polymer Electrolytes for Protecting Zn Metal Anodes from the Corrosion of Water Molecules.

Rechargeable aqueous zinc-ion batteries (RAZIBs) offer low cost, high energy density, and safety but struggle with anode corrosion and dendrite formation. Gel polymer electrolytes (GPEs) with both high mechanical properties and excellent electrochemical properties are a powerful tool to aid the practical application of RAZIBs. In this work, guided by a machine learning (ML) model constructed based on experimental data, polyacrylamide (PAM) with a highly entangled structure was chosen to prepare GPEs for obtaining high-performance RAZIBs. By controlling the swelling degree of the PAM, the obtained GPEs effectively suppressed the growth of Zn dendrites and alleviated the corrosion of Zn metal caused by water molecules, thus improving the cycling lifespan of the Zn anode. These results indicate that using ML models based on experimental data can effectively help screen battery materials, while highly entangled PAMs are excellent GPEs capable of balancing mechanical and electrochemical properties.
