摘 要：Mo+Fe co-doped TiO2 nano powders were synthesised by sol-gel method. X-ray diffraction and transmission electronic microscopy morphologies showed that the Mo+Fe co-doped TiO2 nano powders were pure anatase phase, with the average crystallite size around 20 nm. UV-Vis and photocatalic activity measurements show that this Mo+Fe co-doped TiO2 can absorb visible light, have higher separation efficiency of photoinduced electrons and holes, and possess higher photocatalytic activity compared with anatase TiO2. The enhanced photocatalytic activity of Mo+Fe co-doped TiO2 verified that doping by transition metal ions can also modify the energy band and reduce the recombination centers in TiO2.
