用半导体粒子作光催化剂早已有报道,但在Fujishima用半导体作光电极分解水及Bard将光电化学理论扩展到半导体微粒光催化剂的报道发表之后,半导体光催化才有很大的发展。从太阳能利用的观点来看,半导体光催化有着重大的应用前景,它不仅能 The use of semiconductor particles as photocatalysts has long been reported. However, photocatalysis of semiconductors has been greatly promoted after Fujishima used photoelectrodes to decompose water as semiconductor and Bard extended the theory of photoelectrochemistry to semiconducting particulate photocatalysts. From the point of view of solar energy utilization, semiconductor photocatalysis has great application prospect. It can not only
