摘　　要：P123作为一种重要的模板剂,合成的介孔TiO2纳米材料具有高比表面积、晶粒尺寸小、孔径均一和晶相结构稳定等特性,在水处理领域的研究备受关注。本文综述了以P123为模板剂,溶胶-凝胶法制备介孔TiO2纳米材料的制备方法、结构表征、紫外与可见光催化性能分析,及其在皮革、染料等难降解毒害性废水处理中的应用现状。研究表明,相较于普通的改性TiO2材料,P123模板剂合成的介孔TiO2纳米材料光催化性能优势显著,是一种具有广阔应用前景和发展潜力的新型纳米材料,并有望拓展到天然水体中复杂有机污染物自然降解的研究。P123 is an important template agent,the mesoporous TiO2 nano materials composed by P123 had such features as high specific surface area,small crystalline grain size,even pore diameter and stable crystalline phase structure,etc.It was highly concerned in the researches within the field of water treatment.This thesis comprehensively analysed that with P123 as the template,the preparation method,structural characterization,visible light catalytic performance analysis of mesoporous catalytic materials which were prepared with the sol-gel method,and its application situation in treating the water polluted by degradation-resistant substances like leathers,dyes,etc.In comparison with the ordinary modified TiO2 nanomaterials,the mesoporous TiO2 nano materials which were composed of P123 template was advantageous in photocatalytic performance,that makes it a new nanomaterial of hi-development potential which could be widely applied,and was very likely to be expanded to the research range of the natural degradation of complex organic pollutant in natural water.
