with PEO have acceptable stable periods for practical use. The PEO modified optical transitivity of the hybrid films has heavy effects on the crystallization of TiO2 during structural evolution because of the interaction between PEO and Ti02 . PEO-TiO2 films have better electrochemical activity than the TiO2 equivalent behaved as higher Li + insertion/extraction current density and cyclic......

:Modified TiO2 films have been prepared by combining commercial titania powders (Degussa P25) with sol-gel made by titanium chloride (Ti-sol). The result shows that clusters are formed by nanoparticles and large pores can be seen on the surface of the TiO2 films. The short circuit photocurrent density and photoelectric conversion efficiency of the solar......

预涂SiO2的二氧化钛薄膜光催化活性与结构关系 钟本和1,任成军2 (1.四川大学,化工学院,四川,成都,610065;2.四川大学,化学学院,四川,成都,610064) 摘要:载玻片上浸涂一层常温常压合成的SiO2溶胶后再浸涂TiO2溶胶制备预涂SiO2的TiO2薄膜光催化剂,结果发现浸涂一层SiO2会诱导金红石相TiO2生成,并使TiO2光催化活性提高71.75%,但预涂二层SiO2的TiO2薄膜仅有锐钛型且光催化活性较纯TiO2薄膜降低.这说明适量金红石型/锐钛型的混晶型TiO2具有更好的光催化活性.对TiO2微结构分析显示,TiO2薄膜点阵应变越大,薄膜光催化性能越好.X射线光电子能谱研究表明,预涂一层SiO2的TiO2薄膜Ti3+含量较纯TiO2薄膜高,预涂二层SiO2的TiO2薄膜Ti3+含量较纯TiO2薄膜低.扫描电镜分析说明,预涂SiO2的TiO2薄膜表面颗粒粒径较......
