Development of Heterostructured Photocatalysts for Environmental Pollutant Degradation and Organic Transformation Reactions

Abstract

The increasing levels of environmental contaminants from industrial and urban activities require the creation of innovative materials for sustainable cleanup. Heterostructured photocatalysts have surfaced as effective alternatives because of their excellent light absorption, charge separation, and improved reaction kinetics in visible light. This study explores the creation of innovative heterostructured photocatalysts aimed at effectively breaking down persistent organic pollutants and facilitating organic transformations. The aim is to enhance photocatalytic efficiency by improving the band structures and interfacial interactions of the materials. The creation of heterostructures employing metal oxides, chalcogenides, and various semiconductors was meticulously refined for enhanced stability, recyclability, and swift reaction rates. Experimental findings showed considerable reduction of contaminants like dyes and pharmaceutical residues, along with marked enhancements in reaction kinetics and conversion efficiency. This research offers significant understanding of the structural parameters and conditions necessary for the scalable and sustainable application of heterostructured photocatalysts in both environmental and industrial fields.
