摘　　要：绿色的光催化技术是解决当下能源问题及水环境污染问题的有效方法,然而目前还存在如光催化效率较低,难以实际应用等问题。从光催化基本过程出发,说明了聚苯胺(PANI)作为改性剂对光催化剂光吸收、载流子分离和表面反应的促进作用。在此基础上介绍了PANI改性的光催化剂的合成方法,并对近年来文献报道的通过各种方法制备的PANI修饰的光催化剂在有机污染物降解、产氢和重金属离子去除等方面的应用进行了梳理,最后对PANI修饰的光催化剂现状和未来发展进行了展望。The environmental green photocatalytic technology is an effective way to solve the current energy problems and water pollution problems,however,there are still problems such as low photocatalytic efficiency and difficulty in application.In this paper,the basic photocatalytic process is described,and the modification of polyaniline(PANI)is shown to promote the light absorption,carrier separation and surface reaction of photocatalysts.On this basis,the synthesis of PANI-modified photocatalysts is introduced,and the applications of PANI-modified photocatalysts prepared by various methods for organic pollutant degradation,hydrogen production and heavy metal ion removal reported in the literature in recent years are sorted out.Finally,the current status and future development of PANI-modified photocatalysts are prospected.
