Abstract

The degradation of organic pollutants in water and air using photocatalytic advanced oxidation processes (AOPs) has gained significant attention due to their eco-friendly nature and effectiveness. This paper provides an overview of recent developments in photocatalytic AOPs for the degradation of organic contaminants, highlighting new photocatalyst materials, reaction mechanisms, and improvements in process efficiency. The role of photocatalysis in achieving complete mineralization of organic pollutants is discussed, along with the application of these methods in real-world scenarios, such as wastewater treatment and air purification. The challenges and future directions in this field are also explored, aiming to improve the scalability and commercial viability of photocatalytic AOPs.
