以异丙醇钛为前躯体，十六烷基三甲基溴化铵为模板剂，采用溶胶-凝胶法合成介孔二氧化钛．通过X射线粉末衍射、扫描电子显微镜、透射电子显微镜、比表面积测定仪对样品进行表征．以亚甲基蓝溶液为光催化降解对象，研究二氧化钛用量及不同模板剂对光催化性能的影响．实验结果表明：当催化剂用量在0.50,g/L时，反应4,h后亚甲基蓝的降解率可达到99.1%；在3种模板剂中，以十六烷三甲基溴化铵为模板剂合成的介孔二氧化钛光催化效果最好．

Mesoporous titania was synthesized via a sol-gel method by using isopropyl titanate as the precursor and cetyl trimethyl ammonium bromide as the template. X-ray diffraction(XRD),scanning electron microscope(SEM),transmission electron microscope(TEM)and BET surface area measurement were used to characterize the product. Methyl blue was used as the object of photocatalytic degradation,and the influence of TiO2 dosage and different kinds of template on the photo-catalytic performance was studied. The result indicated that the degradation rate of methyl blue could reached 99.1%within 4,h when the amount of catalyst was 0.50,g/L. Preparation of mesoporous titania using cetyl trimethyl ammonium bromide as template gave the best photocatalytic activity among the three kinds of template.
