Synthesis and Properties of Ni-doping Nano-TiO2 Photocatalysts

摘要：

　　Ni-doping TiO2 photocatalysts were synthesized by sol-gel method and characterized by XRD, Size Distribution and PL instruments.Meanwhile, the degradation of methyl blue (MB) was investigated under fluorescent lamp to test the photocatalytic activity of the samples with different Ni-doping concentration and sintered at different temperature.The results show that the photocatalytic activity of TiO2 photocatalysts is much higher than that of Degussa P25.The optimum preparation parameters are that the pH value is 2.5, Ni: Ti=0.01 (molar ratio) and sintering temperature is 500℃.
