摘要
对SO24-/TiO2固体超强酸光催化剂进行了铈掺杂改性。在铈掺杂情况下,采用沉淀浸渍法,对不同浓度硫酸浸渍液和不同温度焙烧前驱体对催化剂的影响进行了分析。在最佳浓度和最适焙烧温度下,制备了不同铈掺杂量的催化剂,成功的用于10mg/L茜素红溶液降色处理。使其在超过SO24-/TiO2固体超强酸光催化剂降色效果的条件下重复使用,确定了使用次数在铈掺杂为2‰最多。
SO4^2-/ TiO2 solid super acid photocatalyst was modified by doping cerium. In the case of cerium was joined, the influence of catalyst have been done with different concentration of sulfuric acid pickling liquid and the different temperature of the precursor roasted by using precipitation immersion method. In the best concentration and the optimum roasting temperature, the catalyst was prepared with different amount of cerium doped, and was successful in 10mg/L aliza- rin red solution drop color processing. Under the conditions of beyond the discoloring effect of SO4^2- / TiO2 solid super acid photocatalyst,the photocatalyst was repeated used, to determine the amount of cerium doping for the most times of using was 2‰.
