摘　　要：采用溶液-凝胶法分别制备TiO2介孔薄膜和TiO2纳米晶薄膜,其中TiO2介孔薄膜的制备过程中采用PVC-g-POEM为模版。XRD分析结果表明,两者的晶体结构无法明显变化,均为锐钛矿,SEM分析表明TiO2介孔薄膜的孔洞大小及分布均匀。经过染料敏化处理组成光阳极后,TiO2介孔薄膜的吸光性,及光电化学性能明显增强。TiO2 mesoporous films and TiO2 nanocrystal films were prepared by sol-gel method,which the PVC g POEM were used as templates in TiO2 mesoporous films prepared. The XRD result suggested that all the materials were anatase-TiO2. The SEM result showed that the porosity and pore size distribution of the films were even. TiO2 mesoporous films and TiO2 nanocrystal films were applied to dye sensitized solar cell,the properties of optical absorption and photoelec trochemistry preformance were enhanced for the films .
