Over the past decade, nanosized metal oxides, metals, and bimetallic particles have been actively researched as enzyme mimetic nanomaterials. However, common issues with individual nanoparticles (NPs) are stabilization, reproducibility, blocking of active sites by surfactants. These problems promote further studies composite materials, where NPs spread on supports, such graphene derivatives or dichalcogenide nanosheets. Another promising type support for is few-layered hexagonal boron...
Reduced graphene oxide nanosheets decorated with Au–Pd bimetallic alloy nanoparticles are successfully prepared via a chemical approach consisting of reducing the metal precursors using ascorbic acid as reductant at an elevated temperature. The nanocomposite is employed photocatalyst for degradation organic contaminants such phenol, 2-chlorophenol (2-CP), and 2-nitrophenol (2-NP). complete phenol achieved after 300 min under natural sunlight irradiation whereas 2-CP 2-NP completed 180 min....

Efficient electrochemical splitting of water with exceptional durability can be a solution for growing global demand energy. Herein, we systematically investigated the influence supporting two-dimensional (2D) substrate (rGO, g-C3N4, BCN, MoS2, and WS2) on electrocatalytic performance CoS2 nanoparticles (NPs) overall splitting. CoS2NPs decorated onto rGO, WS2 sheets were synthesized by adopting facile hydrothermal technique using cobalt salt sulfur source as precursors. Compared to...
This work describes a practical methodology for C-C bond formation reactions with the aid of biogenic palladium nanoparticles, which are synthesized by using phytochemicals extracted from two common plant species. Comparative studies have been done on activity species (Ocimum sanctum and Aloe vera) in generation nanoparticles via ex situ methods. The structural morphological characteristics examined UV/visible spectroscopy, powder X-ray diffraction, photoelectron Fourier transform infrared...
Herein, a flexible high-performance supercapacitor cell using nanostructured CuCo-layered double hydroxide (LDH) as power source electrode material is reported for the first time, where CuCo-LDH hollow nanopolyhedrons are developed by tuning Cu/Co ratio in LDH host layers.
