摘　　要：介绍了光催化剂改性和外场耦合光催化技术研究进展。光催化剂改性主要围绕金属离子掺杂、非金属掺杂、半导体复合和表面修饰展开,光催化剂制备方法多样化将是今后的发展方向。揭示了超声波场、磁场、电场和微波场等外场耦合光催化反应机理,其中复合场耦合光催化技术和新型光催化反应器设计成为未来应用外场耦合光催化降解有机污染物的研究重点。The modification of photocatalyst and external field assisted photocatalytic were summarized. The modification of photocatalyst on the basis of TiO2 with other semiconductors such as adulterated transition metal-ion or noble metal through superficial deposition and superficial modification along with the immobilization ofphotocatalyst etc. were summarized. Diversity of the preparation methods would be the development trends. The review of photocatalytic degradation of organic pollutants with ultrasonic field, magnetic field, electrochemically field, microwave field was investigated. In particular, the multiple field assisted photocatalytic technology and novel photocatalytic reactor design would be the important issues and research trends in the future.
