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
