用恒电位法制备了多孔Al2O3薄膜, 通过在Al2O3薄膜孔内水蒸汽水解钛酸异丙酯生成了锐钛矿型TiO2微粒, 制备出了Al2O3与TiO2微粒的复合薄膜. 用XRD, SEM, 光电化学方法进行了研究. 实验表明: 该复合薄膜具有光电转换特性, 在光催化、光电化学太阳能转换中具有应用价值.

The porous alumina membrane was made by anodizing pure Al in 0.4 mol/L H3PO4 solution. The anatase TiO2 particles were prepared by hydrolyzing titanium isopropylate with water vapour in the pores of alumina membrane, thus the Al2O3/TiO2 composite membrane was fabricated and characterized with SEM and XRD. The photoelectro-chemical study showed that the Al2O3/TiO2 composite membrane was photoactive.

Key words: alumina membrane, Al2O3/TiO2 composite membrane electrode, photo-elctrochemistry
