采用一步法非离子表面活性剂模板法，结合蒸发诱导自组装(EISA)或水热处理技术，制备了一系列具有二维六方、三维立方和三维互联海绵状孔结构的H3PW12O40-TiO2介观结构材料。对所制备材料的介观结构、形貌、孔隙率、光吸收性能以及组成和结构进行了表征。随后，将该材料成功地应用于模拟太阳光照射下邻苯二甲酸二乙酯(一种内分泌干扰物)在λ>；320 nm和λ>；400 nm区域的降解，并重点考察了结构有序、孔几何、H3PW12O40负载量以及焙烧温度对H3PW12O40-TiO2光催化性能的影响。
A series of mesostructured H3PW12O40–titania materials with two-dimensional hexagonal, three-dimensional cubic, and three-dimensional interconnected sponge-like pore geometries were developed by using a single step nonionic-surfactant-templating strategy combined with evaporation-induced self-assembly (EISA) or hydrothermal treatment technique. The mesostructure, morphology, porosity, optical absorption property as well as composition and structure of as-prepared materials were well-characterized. Subsequently, the materials were successfully applied to the degradation of an aqueous diethyl phthalate (a kind of endocrine disrupting chemical) under the simulated sunlight irradiation at λ>320nm and λ>400nm region, respectively, and special attention was paid to investigate the influences of the structural orderings, pore geometries, H3PW12O40loadings as well as calcination temperature on the photocatalytic performance of the H3PW12O40–titania materials to the target reaction.
