光电催化反应处理染料废水的复合催化剂设计与合成

Design and Synthesis of Composite Catalysts for Treating Dye Wastewater by Photoelectrocatalytic Reaction

为了提高TiO_2的光电催化性能,在二氧化钛里掺杂稀土金属元素和非金属元素以提高其光电催化性能。采用溶胶-凝胶法制备La-N-TiO_2催化剂,通过正交试验设计催化剂的最佳组分和制备条件,在光电协同催化体系中考察催化剂的催化脱色效果。

In order to improve the photoelectrocatalytic performance of TiO2,rare earth metal and non-metal elements were doped into titanium dioxide to improve its photoelectrocatalytic performance.The La-N-TiO2 catalyst was prepared by sol-gel method.The optimum components and preparation conditions of the catalyst were designed by orthogonal experiment.The catalytic decolorization of the catalyst was investigated in the photoelectrocatalytic system.
