Semiconductor photocatalysis was attracted more attentions due to the potential applications in the renewable energy production and environmental purification. The development of visible-light-driven photocatalysts become a hot topic in this field. In this paper, the photophysical and photocatalytic properties of the visible-light driven complex metal oxides photocatalysts will be discussed. We focus on （1） silver salt photocatalytic materials; （2） composite photocatalysts and （3） antimonite acid photocatalyst. The enhanced photocatalytic performance were achieved by improving the preparation method, making composites and doping nonmetal element.
