Tantalumoxide (Ta2O5) thin filmphotocatalysts were prepared on single crystal Si(110) substrates via sol-gel and spin coating methods. Ta2O5 crystallinity was improved, and the crystal size became larger with the increasing of heat treating temperature. The interface diffusion and reaction of the film were studied by using Auger electron spectroscopy (AES) depth profile and line shape analysis. Diffusion was dominant at the interface layer when the calcination, temperature was below 700 ℃. When the temperature reached 800 ℃, both interface diffusion and reaction occurred. The photocatalytic activity was studied using aqueous salicylic acid as a degradation probe molecule under UV-light irradiation. It was found that Ta2O5/Si filmshowed a photocatalytic activity similar to that of TiO2/Si film.

Keywords: Ta2O5/Si thin film   Auger electron spectroscopy   Interface diffusion   Interface reaction   Photocatalytic activity
