抄録

S-doped titanium dioxide thin films were found to undergo hydrophilic conversion under visible light irradiation. The water contact angle for the S-doped TiO₂ thin film reached to 15° under visible light irradiation. The photocatalyzed decomposition of acetaldehyde (ALD) in gas phase on TiO₂ thin films was investigated in a batch-type photocatalytic reactor. The photocatalytic activities of TiO₂ thin films for decomposition of ALD were investigated by analyzing amount of ALD consumed and CO₂ generated under visible light irradiation at wavelengths longer than 420 nm.<br>
