Abstract To address global pollution caused by contaminants in water bodies, it is crucial to develop an efficient and environmentally friendly treatment process for wastewater from various industries. Advanced oxidation processes (AOPs) have proven be highly effective due their high efficacy the absence of secondary pollutants. Different methods such as ozone, Fenton, electrochemical, photolysis, sonolysis can used AOPs degrade emerging pollutants that are resistant conventional methods. In recent years, nanotechnology has emerged a viable solution, with nanomaterials being developed treatment. Among them, copper‐based nanocatalysts shown great potential AOPs. This review focuses on progress mechanisms via It also discusses challenges associated oxidation, electrochemistry, photocatalysis processes. Copper‐based modified enhance catalytic activity, selectivity, stability, leading improved performance They promising results degrading like pharmaceuticals, pesticides, dyes. However, practical application these still faces challenges, including cost synthesis, nanoparticle toxicity, scalability issues. More research needed improve utilization addition, Cu‐based catalysts magnetic properties offer advantage easy recovery reusability incorporated into membranes, forming systems recycling. Heterogeneous diverse structures, ternary or quaternary systems, widely used. remain identifying suitable coupling pairs understanding complex involved constructing heterogeneous interfaces without generating defects. Therefore, thorough catalyst‘s band structure developing structures. Furthermore, implications synthesis raw materials should considered preparation transition metal catalysts, relevant analysis data optimizing degradation conclusion, hold With properties, reusability. costs, issues need addressed. Further overcome optimize
