摘要
继TiO2光催化剂以后的第二代光催化剂-可见光光催化剂由于可以直接利用太阳光对污染物进行降解,甚至可以分解水产生氢能,而成为当今环境领域的研究热点.本文综述了近年来非TiO2可见光响应的氧化物催化剂的研究现状,包括金属氧化物、复合氧化物、杂多酸、卤氧化物的研究进展;概述了其氧化物的制备方法、光催化特性及机理;最后对其氧化物可见光光催化研究进行了展望.
Because the second generation photocatalyst can use sunlight directly to degrade pollutants, or even decompose water to produce hydrogen; they have become the hot spot in environment research following TiOz which is called the first generation photocatalyst, can only be excited under ultraviolet irradiation. In this pa- per, research on non-Ti02 second generation semiconductive oxide catalysts, such as metal oxides, composite oxides, heteropolyacid acid and halogen oxides, are reviewed. Finally, problems and prospects of the second generation photocatalysts are revealed.
