以溶胶—凝胶法制得锐钛矿型结构的TiO2 glass膜 ,用于以 2 5 0W高压汞灯作为光源的不同初始浓度的茜素红水溶液的光催化降解实验。结果表明 ,染料茜素红的光催化降解过程符合零级反应动力学模型。
Anatase-type TiO2 glass films were prepared by sol-gel method. The photocatalysts were used for the photocatalytic degradation of alizarin red aqueous solutions with different initial concentrations of 250W high pressure mercury lamp. The results show that the photocatalytic degradation process of alizarin red dye conforms to the zero-order reaction kinetic model.
