A comprehensive review on photocatalytic degradation of organic pollutants and microbial inactivation using Ag/AgVO3 with metal ferrites based on magnetic nanocomposites

Abstract

AbstractRecent reviews have given a lot of attention to semiconductor photocatalysts’ applicability in environmental applications. These reviews are largely concerned with the geometry, layout, and manufacturing of semiconductors. However, it is necessary to evaluate recent studies on semiconductor photocatalysis. The new study focuses on crucial topics that have received scant consideration in past studies. It provides essential knowledge on microbial and pollutant exposure as well as the pros and downsides of conventional, pharmaceutical, and microbiological methods for removing them. The photocatalyst dose, starting initial concentration, acidity liquid, ambient lighting, oxygen concentration, Hydroxyl radicals’ addition, instant photolysis, and catalyst loading were a few of the operating factors that were briefly discussed. This in-depth analysis provides examples of the different semiconductor substitution techniques. Heterogeneous nanoparticles with a supported or core/shell structure have also been thoroughly investigated. The types of heterojunctions photocatalysts like “p-n, type I, type II, and Z-scheme heterojunctions” and others. Additionally, the Ag-AgVO3 nanoparticles employed for bacterial degradation are addressed. Moreover, the application of the nanocomposites is discussed too with the adsorption kinetics in which its efforts express the parameters in progress.
