摘要

TiO₂ thin film photocatalysts coated onto glass plates were prepared by thermal decomposition of tetraisopropyl orthotitanate with a dip-coating process. In this Letter, the mechanism for photoinduced hydrophilicity of TiO₂ film is clarified by adding the extra H ₂O₂ on TiO₂ surface. Results show that the photoinduced hydrophilicity of TiO₂ film is inhibited with the presence of H₂O₂. The amount of Ti-OH bonds on the surface oppositely increased by the addition of H₂O₂. It indicates the photoinduced hydrophilicity of TiO₂ results from surface oxygen vacancy, not Ti-OH bonds.
