Physicochemical, steric, and energetic characterization of kaolinite based silicate nano-sheets as potential adsorbents for safranin basic dye: effect of exfoliation reagent and techniques.

Kaolinite was subjected to advanced exfoliation processes to form separated nano-silicate sheets (EXK) with enhanced physicochemical properties as adsorbents. This involved the incorporation of different exfoliating agents, urea (U/EXK), KNO3 (N/EXK), and CTAB (C/EXK), highlighting their impacts on their textural and surficial properties as adsorbents for safranin dye. The applied characterization techniques confirmed the higher exfoliating degree of C/EXK, followed by N/EXK and U/EXK. This appeared significantly in the determined surface area (55.7m2/g (C/EXK), 36.7m2/g (U/EXK), and 47.1m2/g (N/EXK)) and adsorption performances. The C/EXK structure displayed a better safranin uptake capacity (273.2mg/g) than N/EXK (231mg/g) and U/EXK (178.4mg/g). Beside the remarkable differences in textural properties, the advanced mathematical modeling and the corresponding steric and energetic parameters illustrate the mentioned uptake properties. The interface of C/EXK is highly saturated by active uptake sites (Nm = 158.8mg/g) as compared to N/EXK (109.3mg/g) and U/EXK (93.4mg/g), which is in agreement with the characterization findings and the expected higher exposure of siloxane groups. Each of these sites can be filled with four dye molecules using C/EXK and N/EXK, which implies the vertical orientation of these adsorbed ions and the effective operation of multi-molecular mechanisms. The energetic (ΔE < 40kJ/mol) and thermodynamic investigations indicate the spontaneous, physical, and exothermic uptake of safranin molecules by EXK particulates. These mechanisms might involve dipole bonding (2-29kJ/mol), electrostatic attraction (2-50kJ/mol), van der Waals forces (4-10kJ/mol), and hydrogen bonding (<30kJ/mol).

Peroxidase-Mimetic Iron Silicate Nanosheets Coordinated with Indocyanine Green for Enhanced Anti-Tumor Therapy.

The versatile element composition and multifunctional properties of biodegradable silicates have attracted significant attention in cancer therapeutics. However, their application as nanozymes is often limited by suboptimal catalytic efficiency and insufficient intratumoral retention. In this study, the hydrothermal synthesis of iron silicate (FeSi) nanosheets are reported exhibiting exceptional peroxidase (POD)-like activity (136.7Umg-1), outperforming most reported iron-based nanozymes. Density functional theory calculations revealed that the introduction of Si into the catalyst enhances H2O2 adsorption and dissociation of Fe sites, leading to superior POD performance. Furthermore, the FeSi nanosheets are modified with Indocyanine Green (ICG) to facilitate targeted aggregation-potentiated therapy. The integration of ICG improved tumor penetration and retention of the FeSi nanosheets, significantly increasing their reactive oxygen species production and bolstering therapeutic efficacy.

Tree-inspired semiconductor-on-ceramic 2D/1D heterostructure for efficient CO2 photoreduction

Two-dimension nanosheets are ideal photocatalysts for CO2 reduction due to their high exposure of active sites and short charge transfer pathway. However, 2D photocatalysts have a tendency to agglomeration, thus compromising the performance of photocatalytic CO2 reduction. Trees, one of the most important plants for photosynthesis, have a unique “leaf-on-branch” structure. This unique two-dimension/one-dimension (2D/1D) configuration maximizes the adsorption of CO2 molecules and light harvesting. Herein, a tree-inspired semiconductor-on-ceramic 2D/1D heterostructure for efficient photocatalytic CO2 reduction is reported. The cobalt silicate (CoSi) nanosheets (∼0.68 nm) are in situ grown on the surfaces of hydroxyapatite (HAP) nanowires, creating a well-defined 2D/1D hierarchical structure. The vertical alignment of ultrathin CoSi nanosheets on the HAP nanowires effectively suppresses their agglomeration, leading to a large BET surface area (106.45 m2/g) and excellent CO2 adsorption (8.00 cm3 g−1). The results of photoelectrochemical characterization demonstrate that the 2D/1D hierarchical structure is powerful to expedite charge transfer. As a result, the gas generation rate of CO is as high as 28780 μmol g−1 h−1 over the CoSi-on-HAP 2D/1D heterostructure. In addition, the electron transfer mechanism and reaction pathways of CO2 reduction are revealed by in situ irradiated XPS and in situ DRIFT spectra.

Surface engineering of zinc plate by self-growth three-dimensional-interconnected zinc silicate nanosheets effectively guiding the deposition of zinc ion for aqueous Zn metal battery

Among battery technologies, aqueous zinc ion batteries (AZIBs) have hit between the eyes in the next generation of extensive energy storage devices due to their outstanding superiority. The main problem that currently restricts the development of AZIBs is how to obtain stable Zn anodes. In this study, taking the improvement of a series of problems caused by the physically attached artificial interfacial layer on Zn anode as a starting point, a nanosheet morphology of ZnSiO3 (denoted as ZnSi) is constructed by self-growth on Zn foil (Zn@ZnSi) by a simple hydrothermal reaction. The ZnSi nano-interfacial layer effectively slices the surface of the Zn foil into individual microscopic interfacial layers, constructing abundant pores. The nanosheets of Zn@ZnSi construct rich nanoscale Zn2+ transport channels, which provide higher electron and ion transport paths, thus achieving the effect of effectively homogenizing the electric field distribution and decreasing the local current density. Thanks to its inherent and structural properties, the Zn@ZnSi anode has a high specific capacity and good cycling stability compared with the Zn electrode. The lifetime of the Zn@ZnSi//Zn@ZnSi symmetric cell is much higher than that of the Zn//Zn symmetric cell at 1 mA cm−2. The capacity of the Zn@ZnSi//NH4V4O10 full cell can still reach 98 mAh g−1 after 1000 cycles at 1 A/g. The low-cost and scalable synthesis of ZnSi nano-interfacial layer on Zn is expected to provide new perspectives on interfacial engineering for Zn anodic protection.

Superfast Zincophilic Ion Conductor Enables Rapid Interfacial Desolvation Kinetics for Low-Temperature Zinc Metal Batteries.

Low-temperature rechargeable aqueous zinc metal batteries (AZMBs) as highly promising candidates for energy storage are largely hindered by huge desolvation energy barriers and depressive Zn2+ migration kinetics. In this work, a superfast zincophilic ion conductor of layered zinc silicate nanosheet (LZS) is constructed on a metallic Zn surface, as an artificial layer and ion diffusion accelerator. The experimental and simulation results reveal the zincophilic ability and layer structure of LZS not only promote the desolvation kinetics of [Zn(H2O)6]2+ but also accelerate the Zn2+ transport kinetics across the anode/electrolyte interface, guiding uniform Zn deposition. Benefiting from these features, the LZS-modified Zn anodes showcase long-time stability (over 3300h) and high Coulombic efficiency with ≈99.8% at 2mA cm-2, respectively. Even reducing the environment temperature down to 0°C, ultralong cycling stability up to 3600h and a distinguished rate performance are realized. Consequently, the assembled Zn@LZS//V2O5-x full cells deliver superior cyclic stability (344.5 mAh g-1 after 200 cycles at 1 A g-1) and rate capability (285.3 mAh g-1 at 10 A g-1) together with a low self-discharge rate, highlighting the bright future of low-temperature AZMBs.

F‐Doped Calcium Silicate Enabling Fast Ion Deposition Kinetics for Highly Reversible Zinc Metal Batteries

AbstractAqueous zinc ion batteries (AZIBs) are subject to various unwanted side reactions, including dendrite growth, hydrogen evolution, and corrosion passivation, due to the highly active Zn anode. While constructing an artificial interface layer (AIL) can address these problems, the compromise in Zn deposition kinetics is considerable. Herein, F‐doped modified hydrated calcium silicate (F‐CSH) nanosheets are designed to enhance Zn2+ ion deposition kinetics. Combined with theoretical calculations, it is verified that the F‐doped contributes to higher interface adsorption energy with Zn metal and lower ion diffusion barrier, favoring faster charge transfer compared to non‐F‐doped counterparts. Additionally, the strong interaction between zincophilic F and Zn facilitates rapid desolvation of Zn2+ and promotes the deposition between the Zn metal and F‐CSH interphases. As a result, the F‐CSH layer maintains the stability on the Zn surface, enabling fast and reversible Zn deposition. The F‐CSH@Zn anode exhibits a long lifespan of over 2800 h at 5 mA cm−2, while running more than 2500 cycles at a ≈100% Coulombic efficiency. This work highlights the importance of constructing AIL with strong interaction with Zn2+/Zn in improving the interphase kinetics of zinc anode for realizing the stability of AZIBs.

Boosting charge transfer of NiAl-LDH by silicate nanosheets for enhanced photocatalytic CO2 reduction

The layered double hydroxide (LDH) nanosheets are ideal for photocatalytic CO2 reduction. How to suppress the spontaneous agglomeration of LDH remains a challenge. Herein, this work reports that the insulated calcium silicate hydrate (CSH) nanosheets effectively suppress the agglomeration of NiAl-LDH nanosheets by an electrostatic self-assembly. The charge transfer of NiAl-LDH/CSH is effectively promoted, as verified by photoelectrochemical characterizations. As a result, the CO and H2 generation rates from photocatalytic CO2 reduction are as high as 3432 and 1411 μmol g−1h−1, which are ∼2.4 times higher than that of the pure NiAl-LDH.

Nanoclay-Reinforced Nanocomposite Nanofibers—Fundamentals and State-of-the-Art Developments

Nanoclays are layered mineral silicates, i.e., layered silicate nanosheets. Nanoclays such as montmorillonite, bentonite, kaolinite, etc., have been used as reinforcements in the nanofibers. Numerous polymers have been used to fabricate the nanofibers, including poly(vinylidene fluoride), poly(vinyl alcohol), polycaprolactone, nylon, polyurethane, poly(ethylene oxide), and others. To develop better compatibility with polymers, nanoclays have been organo-modified prior to reinforcement in the nanofiber matrices. This state-of-the-art review highlights the fundamentals, design, fabrication, and characteristics of the polymer/nanoclay nanofibers. The nanoclay filled nanocomposite nanofibers have been fabricated using electrospinning and other fiber processing techniques. The electrospinning technique has been preferred to form the nanoclay-filled nanofibers, owing to the better control of processing parameters and resulting nanofiber properties. The electrospun polymer/nanoclay nanofibers usually have fine nanoparticle dispersions, microstructures, smooth textures, and narrow diameters. The physical properties of the designed nanofibers depend upon the processing technology used, solvent, solution/melt concentration, flow rate, spinning speed, voltage, and other process parameters. Hence, this review attempts to assess a literature-driven consequence of embedding nanoclays in the polymeric nanofibers in a broad context of the application of these fibrous materials. Conclusively, to design the polymer/nanoclay nanofibers, montmorillonite nanoclay has been observed as a nanofiller in most of the studies, and, similarly, the electrospinning technique was preferred as a fabrication technique. Almost all the physical properties of the nanofibers studied revealed dependences upon the choice of the polymer matrix for nanofiber formation as well as the nanoclay contents, modification, and dispersion state. Accordingly, the nylon/nanoclay nanofibers have been investigated for nanofiller dispersion, mechanical properties, and thermal profiles. The antibacterial properties were among the prominent features of the poly(vinyl alcohol)/nanoclay nanofibers. The poly(vinylidene fluoride)/nanoclay systems were explored for the microstructure, crystallinity, and piezoelectric properties. The polycaprolactone/nanoclay nanofibers having fine microstructure were capable of forming tissue engineering scaffolds. The drug delivery and sound absorption properties were noticeable for the polyurethane/nanoclay nanofiber systems. Moreover, the poly(lactic acid)/nanoclay nanofibers were found to have prominent biodegradability and low gas permeability features. The resulting polymer/nanoclay nanocomposite nanofiber systems found potential for the technical applications of sensors, packaging, tissue engineering, and wound healing. However, thorough research efforts have been found to be desirable to find the worth of polymer/nanoclay nanofibers in several concealed technological sectors of energy, electronics, aerospace, automotives, and biomedical fields.

Synthesis of nickel silicate/reduced graphene oxide composite for long-life lithium-ion storage

To improve the electrochemical performance of nickel silicate as anode material of lithium ion batteries, nickel silicate nanosheets anchored on reduced graphene oxide composite is synthesized via hydrothermal method using sandwich-like silica/graphene oxide as raw material. Nickel silicate nanosheets anchor on both sides of the reduced graphene oxide and cross each other to form net-like structure. The thickness of the nanosheets is about 15 nm. The composite shows an optimal electrochemical performance as lithium ion battery anode material. The initial capacity is 1525.7 mAh g−1 and the capacity retains 815.5 mAh g−1 after 50 cycles at the current density of 50 mA g−1. It exhibits good rate performance. When the current density is increased to 5000 mA g−1, the average capacity is as high as 415.8 mAh g−1. The composite also demonstrates an exceptional high cycling stability with the capacity of 423.4 mAh g−1 after 1000 cycles.

In‐Situ Constructing A Heterogeneous Layer on Lithium Metal Anodes for Dendrite‐Free Lithium Deposition and High Li‐ion Flux

AbstractConstructing efficient artificial solid electrolyte interface (SEI) film is extremely vital for the practical application of lithium metal batteries. Herein, a dense artificial SEI film, in which lithiophilic Zn/LixZny are uniformly but nonconsecutively dispersed in the consecutive Li+‐conductors of LixSiOy, Li2O and LiOH, is constructed via the in situ reaction of layered zinc silicate nanosheets and Li. The consecutive Li+‐conductors can promote the desolvation process of solvated‐Li+ and regulate the transfer of lithium ions. The nonconsecutive lithiophilic metals are polarized by the internal electric field to boost the transfer of lithium ions, and lower the nucleation barrier. Therefore, a low polarization of ≈50 mV for 750 h at 2.0 mA cm−2 in symmetric cells, and a high capacity retention of 99.2 % in full cells with a high lithium iron phosphate areal loading of ≈13 mg cm−2 are achieved. This work offers new sights to develop advanced alkali metal anodes for efficient energy storage.

Optimizing Pd-Catalyst Activity The cover image represents a plate-like Pd particle supported on layered silicate nanosheets that require at least six layers of assembly to exhibit a metallic character and hence, a maximum catalytic activity in dehydro-coupling formic acid in aqueous media, as reported in article number 2202368 by Esmail Doustkhah, Nao Tsunoji, M. Hussein N. Assadi, and Yusuke Ide.

Surfactant assisted exfoliation of near infrared fluorescent silicate nanosheets.

Fluorophores that emit light in the near infrared (NIR) are advantageous in photonics and imaging due to minimal light scattering, absorption, phototoxicity and autofluorescence in this spectral region. The layered silicate Egyptian blue (CaCuSi4O10) emits as a bulk material bright and stable fluorescence in the NIR and is a promising NIR fluorescent material for (bio)photonics. Here, we demonstrate a surfactant-based (mild) exfoliation procedure to produce nanosheets (EB-NS) of high monodispersity, heights down to 1 nm and diameters <20 nm in large quantities. The approach combines planetary ball milling, surfactant assisted bath sonication and centrifugation steps. It avoids the impurities that are typical for the harsh conditions of tip-sonication. Several solvents and surfactants were tested and we found the highest yield for sodium dodecyl benzyl sulfate (SDBS) and water. The NIR fluorescence emission (λem ≈ 930-940 nm) is not affected by this procedure, is extremely stable and is not affected by quenchers. This enables the use of EB-NS for macroscopic patterning/barcoding of materials in the NIR. In summary, we present a simple and mild route to NIR fluorescent nanosheets that promise high potential as NIR fluorophores for optical applications.

Orange waste Biochar-Magnesium Silicate (OBMS) composite for enhanced removal of U(VI) ions from aqueous solutions

The removal of toxic radioactive pollutants from water sources for further disposal and treatment is a critical issue. Development of an effective adsorbent with high adsorption capacity and stability for the adsorption of hexavalent uranium, U(VI) ions is interesting research task. In this study, orange waste biochar‑magnesium silicate (OBMS) composite was prepared by simple hydrothermal method and utilized for U(VI) ions adsorption removal from aqueous solution. The successfully synthesized OBMS composite consists of graphitic carbon biochar and interconnected magnesium silicate nanosheets exhibiting 73.9 m2/g surface area with H3 type hysterias loop suggests mesoporous texture having stacked and agglomerated magnesium silicate layers covered by biochar. The prepared composite was used to study the influence of pH, U(VI) ion concentration, mass of adsorbent, presence of other cations and determination of thermodynamic functions. It was observed that OBMS composite showed high adsorption capacity (Langmuir adsorption capacity of 352.6 mg/g at 298 K, pH 4) irrespective of presence of other cations. A series of batch experiments and characterization results revealed that the superior adsorption performance of the composite is due to interaction between U(VI) ions and functional groups presented on the OBMS composite surface. The observed results suggesting the interaction between U(VI) ions OBMS surface functional groups such as CC, COH, CO, MgOSi and Mg(OH)2 is playing a key role in removal of U(VI) ions from aqueous solution. This low-cost and easily synthesized absorbent has a great potential for use in the remediation of radioactive U (VI) ions in aquatic environments.

Self-swelling derived frameworks with rigidity and flexibility enabling high-reversible silicon anodes

ABSTRACT Silicon is recognized as the most advantageous next-generation anode material for LIBs in terms of its extremely high theoretical capacity and appropriate operating voltage. However, the application of Si anode is limited by huge volume expansion emerging with cycling, which in turn induces the collapse of the electrode structure, resulting in rapid capacity decay. Here, we report a strategy using self-swelling artificial laponite to prepare a laponite/MXene/CNT composite framework with both rigidity and flexibility, which can excellently address these challenges of Si anode. The self-swelling artificial laponite participates in the construction of hierarchical and porous structures, providing sufficient buffer space to mitigate the volume expansion of the Li x Si alloying reaction. Meanwhile, tough and tightly cross-linked silicate nanosheets can improve the mechanical strength of the framework for strong structural stability. More importantly, the negative charge between the layers of artificial laponite can effectively promote fast Li-ion transport in the electrode. This free-standing silicon anode enables the preparation of high areal capacity electrodes to further enhance the energy density of LIBs and a higher reversible capacity of 2381.8 mAh/g at 0.1 C after 50 cycles with an initial coulombic of 85.6%. This work provides a simple and practical fabrication strategy for developing high-performance Si-based batteries, which can speed up their commercialization. A 3D free-standing silicon anode with both rigidity and flexibility has been constructed via self-swelling artificial laponite, which enables the preparation of high areal capacity electrodes to further enhance the energy density of LIBs.

Novel 2D Layered Manganese Silicate Nanosheets with Excellent Performance for Selective Catalytic Reduction of NO with Ammonia

AbstractTwo‐dimensional (2D) catalysts are highly attractive for their great potential in environment remediation and energy conversion. In this work, a novel layered manganese silicate (MnSiO3) catalyst was synthesized by hydrothermal method using silica in vermiculite, a layered silicate clay mineral, as the lattice‐matching matrix and silicon source. The epitaxial growth of MnSiO3 is confined in the 2D directions, resulting in the morphology of vermiculite crystal thin nanosheets. The physichemical characterization results showed that MnSiO3 possessed higher Mn4+ content, acidic sites and reducing substances than that of MnOx/SiO2. The MnSiO3 therefore exhibited 100 % NO conversion rate with 85 % N2 selectivity at 150 °C in the NH3−SCR process. In situ DRIFTS studies show that MnSiO3 has strong NO adsorption capacity and NH3 activation capacity, which is beneficial to the improvement of NH3−SCR activity.

Visible Light Active Magnesium Silicate–Graphitic Carbon Nitride Nanocomposites for Methylene Blue Degradation and Pb2+ Adsorption

Magnesium silicate nanosheets (MgSiNS) and graphitic carbon nitride (g-C3N4) nanocomposites were produced by varying different weight percentages of g-C3N4. The obtained nanocomposites were characterized by various techniques such as X-Ray diffraction (XRD), Fourier transformed infrared spectroscopy (FT-IR), diffuse reflectance UV–vis spectroscopy (DR UV–vis), N2-physisorption, transmission electron microscopy (TEM), and X-ray photon spectroscopy (XPS). The photocatalytic activities of the nanocomposites were measured using visible light irradiation to degrade methylene blue (MB) and Pb2+ adsorption in aqueous solution. The ideal physicochemical properties such as porosity, band gap energy, and functional groups in the MgSiNS-GN20 composite (80% MgSiNS and 20 wt % of g-C3N4) offered high Pb2+ adsorption (0.005 mol/g) and excellent MB degradation efficiency (approximately 93%) at pH 7 within 200 min compared to other composites. In addition, the influences of different reaction parameters such as the effect of pH, the load catalyst, and the concentration of MB and Pb+2 ions were examined. The obtained results indicate that inexpensive and eco-friendly MgSiNS and g-C3N4 composites could be recycled several times, hence representing a promising material to purify water from both organic and inorganic contaminants.

Disentangling the Orientations of Spectrally Overlapping Transition Dipoles in Dense Dye Layers

The transition dipole orientations of dye assemblies in heterostructures have a crucial impact on the efficiency of novel optoelectronic devices such as organic thin-film transistors and light-emitting diodes. These devices are frequently based on heterojunctions and tandem structures featuring multiple optical transitions. Precise knowledge of preferred orientations, spatial order, and spatial variations is highly relevant. We present a fast and universal large-area screening method to determine the transition dipole orientations in dye assemblies with diffraction-limited spatial resolution. Moreover, our hyperspectral imaging approach disentangles the orientations of different chromophores. As a demonstration, we apply our technique to dye monolayers with two optical transitions sandwiched between two ultrathin silicate nanosheets. A comprehensive model for dipole orientation distributions in monolayers reveals a long-range orientational order and a strong correlation between the two transitions.

Fe 3 O 4 Nanoparticles Enhanced Amorphous Ferric Silicate/Reduced Graphene Oxide for High‐Performance Lithium‐Ion Storage

Ferric silicate (FS) has been explored as a potential lithium ion batteries candidate for its environment benign, low cost, rich reserves, and high capacity. Despite these advantages, poor electronic conductivity and large volume variation obstruct its practical utilization. To improve its electrochemical performance, a unique hybrid structure with Fe3O4@ferric silicate nanosheets anchored on the reduced graphene oxide ([email protected]/RGO) is fabricated. The disordered amorphous nanosheet structure of FS not only shortens the transferred length for lithium ions but also facilities the Li+ diffusion and can effectively keep the structure integrity. RGO substrate ameliorates the electronic conductivity and slackens the strain upon cycling. Fe3O4 (FO) nanoparticles embedded in FS further boost the electronic conductivity and the lithium storage capability. The synergistic effects bestow the composite superior electrochemical properties. [email protected]/RGO shows high reversible capacity of 1113 mA h g−1 at 0.2 A g−1, an excellent rate performance of 681 mA h g−1 at 2 A g−1, and a splendid cycling stability with a capacity of 859 mA h g−1 at 1 A g−1 after 800 cycles.

Magneto-Orientation of Magnetic Double Stacks for Patterned Anisotropic Hydrogels with Multiple Responses and Modulable Motions.

Reported here is a multi‐response anisotropic poly(N‐isopropylacrylamide) hydrogel developed by using a rotating magnetic field to align magnetic double stacks (MDSs) that are fixed by polymerization. The magneto‐orientation of MDSs originates from the unique structure with γ‐Fe2O3 nanoparticles sandwiched by two silicate nanosheets. The resultant gels not only exhibit anisotropic optical and mechanical properties but also show anisotropic responses to temperature and light. Gels with complex ordered structures of MDSs are further devised by multi‐step magnetic orientation and photolithographic polymerization. These gels show varied birefringence patterns with potentials as information materials, and can deform into specific configurations upon stimulations. Multi‐gait motions are further realized in the patterned gel through dynamic deformation under spatiotemporal light and friction regulation by imposed magnetic force. The magneto‐orientation assisted fabrication of hydrogels with anisotropic structures and additional functions should bring opportunities for gel materials in biomedical devices, soft actuators/robots, etc.
