A Brief Review: Understanding the Mechanisms of Methyl Orange Photodegradation on Zinc-Doped TiO2 Surfaces

Abstract

The photocatalytic degradation of organic pollutants represents a promising avenue for addressing environmental contamination. In this study, we delve into the mechanisms underlying the photodegradation of methyl orange on zinc-doped titanium dioxide (Zn-TiO2) surfaces. Zinc doping has emerged as a strategy to enhance the photocatalytic activity of TiO2 by modifying its electronic and structural properties. Through a combination of experimental investigations and theoretical modeling, we elucidate the intricate processes governing the interaction between methyl orange molecules and Zn-TiO2 surfaces under irradiation. Our findings shed light on the role of zinc doping in facilitating photoinduced charge transfer processes, surface adsorption kinetics, and the generation of reactive oxygen species. This enhanced understanding of the mechanisms involved in methyl orange photodegradation on Zn-TiO2 surfaces provides valuable insights for the rational design and optimization of advanced photocatalytic materials for water purification and wastewater treatment applications.
