摘要
Rutile TiO2 was obtained from acid treated BaTiO3 under hydrothermal treatment. The influences of acid concentration, temperature and treating time on the obtained products' crystalline phase, morphologies, surface properties and photocatalytic activities were investigated. Higher nitric acid concentration was in favor of purer and finer rutile particles, while hydrothermal temperature and time affect it little. FE-SEM observation shows that, uniform TiO2 nanorods are obtained with lower acid concentration and smaller TiO2 nanoparticles formed with higher concentration. Their photocatalytic activities were evaluated by the decomposition of gaseous 2-propanol (IPA) under UV irradiation. Rutile TiO2 treated with higher acid concentration exhibits better photocatalytic performances.
