The preparation of heterojunction photocatalytic oxidation catalysts composed of metal compounds and TiO2 such as Bi/Ti,Ag/Ti and Cu/Ti were briefly introduced.The optical properties and photocatalytic applications of such heterojunction catalysts were reviewed highlightly.Among them,Bi/Ti heterojunctions were studied widely.Studies on TiO2 heterojunctions with other composites were still in the exploration stage.Systematic studies on the composition diversity and modulation laws of TiO2 heterojunctions were still the focus of future research.The application of catalysts mainly focused on the degradation of organic dyes,and expanding its photocatalytic applications was also the main direction of future research.
