摘 要: 采用正交试验方法制备纳米二氧化钛/炭材料(TiO2/C)催化剂,用热重分析仪、扫描电镜、X射线衍射及比表面积仪对TiO2/C进行表征,考察了TiO2/C制备条件对甲基橙溶液光/光电催化降解效果的影响。发现了负载物的比表面积对于催化剂的降解率起决定性作用的结果。 The catalyst of nanometer titanium dioxide/active carbon material (TiO2 /C) was prepared by means of orthogonal experimental method. Based on the characterization of TiO2 /C catalyst with TG, SEM, XRD, specific surface area, the effects of the conditions of prepared TiO2/C catalyst on the photocatalysis/ photoelectrocatalysis degradation of methyl orange solution was investigated. The result was obtained that the specific surface areas of catalyst supporter play a decisive role for the degradation efficiency of methyl orange.
