Metal oxide nanoparticles synthesized by the biological method represent most recent research in nanotechnology. This study reports rapid and ecofriendly approach for synthesis of CeO2 mediated using Abelmoschus esculentus extract. The medicinal plant extract acts as both a reducing stabilizing agent. characterization NPs was performed scanning electron microscopy (SEM), X-ray diffraction (XRD), ultraviolet-visible spectroscopy (UV-Vis), Fourier transform infrared (FTIR). vitro cytotoxicity...
2D transition metal dichalcogenides (TMDs) have received widespread interest by virtue of their excellent electrical, optical, and electrochemical characteristics. Recent studies on TMDs revealed versatile utilization as electrocatalysts, supercapacitors, battery materials, sensors, etc. In this study, MoS2 nanosheets are successfully assembled the porous VS2 (P-VS2 ) scaffold to form a /VS2 heterostructure. Their gas-sensing features, such sensitivity selectivity, investigated using quartz...
Abstract An effective and selective method for the oxidation of 5‐hydroxymethylfurfural (HMF) by using hydrogen peroxide (H 2 O ) as liquid oxygen source activated‐carbon‐supported ruthenium (Ru/AC) catalyst was developed. This reaction system allowed HMF to be oxidized in water under mild conditions efficiently, it shown have lower mass‐transfer resistance than gaseous oxygen‐assisted systems. In addition, we could selectively control components products adjusting conditions. We optimized...
Abstract Selective hydrogenation of nitriles is an industrially relevant synthetic route for the preparation primary amines. Amorphous metal–boron alloys have a tunable, glass‐like structure that generates high concentration unsaturated metal surface atoms serve as active sites in reactions. Here, method to create nanoparticles composed mesoporous 3D networks amorphous nickel–boron (Ni‐B) alloy reported. The benzyl cyanide β‐phenylethylamine used model reaction assess catalytic performance....
In this experimental approach, we explored the structures, morphologies, phototoxicities, and antibacterial activities of undoped Mn-doped ceria nanocomposite materials, Mn x Ce 1− O 2. The 2 nanocomposites were synthesized by employing a soft chemical route. Our prime focus was on influence different factors, both physical chemical, i.e., concentration manganese in product, size nanocomposite, drug dose, incubation time, bacterial strains. Different strains selected as biological models...
Abstract Porous nanomaterials with superior peroxidase mimetic activity (nanozyme) at room temperature have gained increasing attention as potential alternatives to natural enzymes. Herein, we report the application of porous iron oxide nanoflakes (IONFs), synthesized using combination solvothermal method and high‐temperature calcination nanozyme for oxidation 3,3′,5,5′‐tetramethylbenzidine (TMB) in presence H 2 O . The four IONF catalysts possess structures a wide pore size distribution...
A series of cobalt-inserted copper zinc ferrites, Cu0.6CoxZn0.4−xFe2O4 (x = 0.0, 0.1, 0.2, 0.3, 0.4) having cubic spinel structure were prepared by the coprecipitation method. Various characterization techniques, including XRD, FTIR, UV-vis and I–V used to investigate structural optical electrical properties, respectively. The lattice constant was observed be decreased as smaller ionic radii Co2+ (0.74 Å) replaced higher Zn2+ (0.82 Å). presence tetrahedral octahedral bands confirmed FTIR...
