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 Herein, the preparation of gold nanoparticles-silk fibroin (SF-AuNPs) dispersion and its label-free colorimetric detection organophosphate pesticide, namely chlorpyrifos, at ppb level are reported. The silk solution was extracted from B. mori after performing degumming, dissolving dialysis steps. This used for synthesis nanoparticles in-situ without using any external reducing capping agent. X-ray Diffractometry (XRD), Field Emission Transmission Electron Microscopy (FETEM) along...
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 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...
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....
Photocatalytic reduction of CO2 with CH4 through the dry reforming methane (DRM) is an attractive approach to recycling greenhouse gases into valuable chemicals and fuels; however, this process quite challenging. Although there growing interest in designing efficient photocatalysts, they are less stable, have lower photoactivity when employed for DRM reactions. Herein, we developed a noble metal-free hierarchical graphitic carbon nitride (HC3N4) loaded cobalt (Co) highly stable...
