Chemical Catalytic Applications of Nanocomposites in Photo Reactors: Review

Abstract

Nanocomposites as a photocatalysts are chosen for the photocatalytic degradation of organic pollutant molecules. Noble metal decorated mixed metal oxides composite and reduced graphene oxide deposited metal oxide nanocomposites are of cost-effective photocatalysts. Nanocomposites are act as better photocatalysts due to their tunable surface characteristics as acidic and basic properties, advanced oxidation or reduction abilities makes them unique approach for heterogeneous photocatalysts. Development of cheaper semiconductor photocatalysts, which are highly effective and reusable photocatalytic applications of nanocomposites under visible light, is very challenging materials. We prepared cost-effective ternary mixed metal oxide nanocomposites chemical catalysts with rGO with heterojunctions of rGO-ZnO-TiO2-Nb2O5 labelled as rGZTNb for efficient photo catalysis in photo reactor under visible light radiations for chemical catalysis. Author described about eh development effect of heterogeneous photocatalysts. Heterogeneous visible light photocatalysts of semiconductor mediated materials at the nanometer scale have paid much attention towards the past decade due to their beneficial strategies in the photocatalytic usage. ZnO and TiO2 along with Nb2O5 nanocomposite combinations as solid powders can significantly enhance light absorption, then separation pairs of electron-hole by photogeneraton.
