Material Design and Mechanism Research for Photocatalytic Degradation of Organic Pollutants

Full Text(PDF, 62KB)

Author: Zhiqing Dong

Abstract: Photocatalysis has emerged as an effective and sustainable approach for the degradation of organic pollutants, addressing global environmental concerns. This study explores the design and mechanisms of photocatalytic materials for efficient pollutant degradation. Traditional photocatalysts, such as TiO₂ and ZnO, exhibit high oxidative potential but suffer from limited visible-light absorption and charge recombination. To overcome these limitations, advanced photocatalytic materials, including narrow-bandgap semiconductors, carbon-based composites, metal-organic frameworks (MOFs), and heterostructured systems, have been extensively developed. Various modification strategies, such as element doping, heterojunction formation, and surface engineering, have further enhanced photocatalytic activity, stability, and pollutant selectivity. The mechanisms underlying photocatalytic degradation involve reactive oxygen species (ROS) generation and pollutant-specific degradation pathways, influenced by catalyst properties, light absorption, and reaction conditions. The study also examines the degradation of various organic pollutants, including industrial chemicals, pharmaceuticals, and environmental contaminants. By advancing material design and optimizing reaction parameters, this research contributes to the development of next-generation photocatalysts with improved efficiency and applicability in large-scale environmental remediation.
