Photocatalytic technology, as a clean, green, and sustainable method for pollutant degradation, has significant scientific research value practical application significance in the field of water pollution control. Currently, focus photocatalysis is on developing efficient, stable, low-cost photocatalysts. Researchers are enhancing light absorption capacity, electron-hole separation efficiency, degradation rate photocatalysts by designing novel photocatalysts, such S-type heterojunctions, Z-scheme structures, precious metal doping, non-metal regulation. The mechanistic study photocatalytic process, especially separation, migration, transfer mechanisms photogenerated carriers, provides theoretical support optimization design At present, there various types catalysts pollutants, including oxide (e.g., TiO2, ZnO), platinum, gold, silver), carbon-based graphene, carbon nanotubes), composite oxide-carbon-based catalysts).Each type catalyst shown performance improving efficiency expanding range, but also faces challenges limited poor stability, high cost. Composite significantly improve through synergistic effects, excelling high-concentration pollutants. Future will further optimizing catalysts, particularly stability. remains research, exploration effects between different materials. same time, issues long-term recyclability, selectivity need to be addressed their large-scale application.
