摘要 以钛酸丁酯和氧化镧为原料,通过一步法合成金红石相TiO2和La/金红石相TiO2。利用XRD、比表面积、DRS、Zeta电位等表征La/金红石相TiO2的光催化活性性能。结果表明,质量分数1.00%的La/金红石相TiO2光催化活性最优。以甲基红、甲基橙和亚基甲蓝为降解目标的光催化,其反应动力学参数与表征结果吻合。 The futile TiO2 and La/rutile TiO2 were synthesized by one-step method. The photocatalytic activity of La /rutile TiO2 were characterized by XRD, specific surface area, DRS, Zate potential, et al. The result shows that the photocatalytic activity of 1.00% La/rutile TiO2 is the best. Besides Methyl orange reaction and Methylene blue trihydrate are degradation of the target. By kinetics parameters of photocatalyzing Methyl orange reaction, the kinetics parameters are similar with the results of characterization such as k and t0.5.
