## Abstract

At present, the contamination of wastewater by persistent organic pollutants is a problem causing significant concern. Advanced oxidation processes have emerged as effective and innovative technologies for the degradation of these pollutants. In these processes, the synthesis and usage of an appropriate catalyst is essential to enhance the generation of reactive species and improve treatment efficiency. In this sense, the use of greener solvents in the synthesis procedure has attracted great interest in recent years, improving the catalyst performance and reducing the associated synthesis impact. Among them, deep eutectic solvents stand out for the synthesis of catalytic materials in advanced oxidation processes for water treatment, offering a sustainable alternative to traditional methods due to their unique properties and low environmental impact. This review summarizes recent advances in this field, highlighting primarily the methods for preparing new catalytic materials using deep eutectic solvents and their application in different types of advanced oxidation processes.
