The Synthesis and Photocatalytic Efficacy of Distinct Nano-Oxides in the Breakdown of Organic Contaminants

Abstract

Nano metal oxides (NMOs), with their unique physico-chemical properties and low toxicity, have become a focus of research in heterogeneous catalysis. Their distinct characteristics, which can be tailored based on size and structure, make them highly efficient catalysts. NMOs have the potential to significantly contribute to the degradation of numerous environmental pollutants through photolytic decomposition. This work comprehensively analyzes the synthesis, catalytic performance, and applications of photocatalytically active metal oxides, specifically titanium, zinc, copper, iron, silver, tin, and tungsten oxides. The primary objective is to demonstrate how the effectiveness of photocatalytic processes can be enhanced and optimized by incorporating metals, non-metals, and metalloids into their structure and forming heterostructures. Furthermore, the aim is to understand the underlying process of photocatalytic oxidation thoroughly. Photocatalysis, a promising approach in advanced oxidation processes, has garnered significant interest in these fields.
