| 摘 要： | 以硫脲、硝酸镍、钛酸四丁酯为原料,用溶胶-凝胶法制备了纯TiO2和不同比例N、Ni掺杂的TiO2的光催化剂样品,用紫外-可见分光光度计进行了表征。结果表明,经过掺杂的TiO2光催化剂的吸收边向可见光方向移动,TiO2可见光催化活性提高,掺杂量为0.15 g,pH=9,温度为30℃时,对亚甲基紫的脱色效果最好。

| Abstract: | With thiourea,nitric acid nickel,tetra butyl titanate ester as raw material and using sol-gel process with different proportion of pure TiO2 and N,Ni TiO2 light catalysts doped samples.By UV-Vis spectra photometry instrument was characterized.Results showed that after doped the absorption of TiO2 light catalyst to visible direction,edge of TiO2 visible catalytic activity improved,doping quantity 0.15 g,pH=9 and for 30 ℃ the methyl violet decoloration rate the best effect. |
