英文摘要：

In recent years, the study on nobel-metal （Au, Ag, Pt, Pd）/TiO2 photocatalysts has becom the research hotspots of TiO2-based visible-light-active photocatalyst. Great progress has been made in both th mental research and application. In this article, we focused on nobel-metal/TiO2 visible light photocatalysts, troduce basic characteristics, such their preparation, photocatalytic mechanism and influencing factors. Their tions involve removing contaminants, sterilization and new energy technologies. e one of e funda- and in- applica-
