Abstract: The progress was made in the area of extending the light absorption of TiO2 into visible light region by methods of metal cation doping, metalloid anion doping, ion implantation and photosensitization. The particular advantage of metalloid anion doping was that the visible-light-activities can be obtained without the lose of UV-light activities. This article mainly summarized the recent progress in TiO2 modification by means of metalloid anion doping and the advance in photocatalytic hydrogen production with the photosensitization semiconductor made in our group. In addition, the effect of metalloid anion doped TiO2 in response to visible light was classified and evaluated. Based on the fact that the construction of inorganic salt-water splitting system without electron donors is a new subject with a view to practical research, the recent advance in the construction of inorganic salt-water splitting system is briefly reviewed while the prospects and existing problems especially for TiO2 photocatalyst are also addressed.
