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。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.
