摘　　要：综述了四氧化三钴光裂解水制氢气和氧气的机理,并介绍了近年来改性四氧化三钴提高光解水制气的方法,在此基础上分析了存在的问题及前进的方向。The conversion of solar energy to hydrogen and oxygen by means of water splitting is considered as an environmental friendly technology for renewable energy.Recently,Co3O4 has been aroused much attention due to its narrow energy band which is greatly beneficial to the excitation by the sunlight.The mechanisms of water splitting by Co3O4 are described.Their influence on the photocatalytic properties and the modifications are put forward.The problems existed are pointed out.The future of water splitting over the Co3O4 is proposed as well.
