A LED visible-light-driven photocatalytic decontamination of azo dyes using Ag/ZnO heterojunction

A LED visible-light-driven photocatalytic decontamination of azo dyes using Ag/ZnO heterojunction

An emerging study is an Ag/ZnO heterojunction photocatalyst for the decomposition prospect of azo dyes in wastewater under visible light. Herein, spherical nanoparticles of the Ag/ZnO of 20–50 nm are synthesised via a green chemical method from a rosin…

Green synthesis of titanium dioxide nanoparticles using Thymus vulgaris leaf extract for biological applications

Green synthesis of titanium dioxide nanoparticles using Thymus vulgaris leaf extract for biological applications

In the last few decades, the biosynthesis of nanoparticles using biological agents such as microorganisms or plant extracts has gained a lot of attention due to the growing need for generating safe and non-toxic substances, cost-effective techniques, e…

A bimetallic PdPt catalyst on CeZrO2/H-ZSM-5 dual support with exceptional activity in low temperature methane oxidation

A bimetallic PdPt catalyst on CeZrO2/H-ZSM-5 dual support with exceptional activity in low temperature methane oxidation

Various techniques were employed to prepare a dual support system of CeZrO2 and H-ZSM-5 (80) including physically mixing, co-precipitation and sonochemical methods, which were followed by the deposition of bimetallic Pd and Pt via wet impregnation to o…

Charge transport properties of interstitially doped graphene: a first-principles study

Charge transport properties of interstitially doped graphene: a first-principles study

The role of interstitial atomic doping on transport properties of graphene was systematically studied using first-principles density functional theory (DFT). The study revealed that interstitial Au doping results in a p-type transfer of holes to graphe…

Studying the structural and optical properties of Er3+ doped TiO2 powders synthesized by the sol-gel process

Studying the structural and optical properties of Er3+ doped TiO2 powders synthesized by the sol-gel process

A series of TiO2:xEr powders (with x from 0% to 1% at.) was synthesised by a simple sol–gel process. The structural and optical properties were studied in detail using diffusion reflection spectroscopy, x-ray diffraction, Raman spectroscopy, high-resol…
