摘要：
TiO(2) film was deposited on titanium substrate by a sol-gel dip-coating process. Photocatalytic activities of the films prepared with and without template were compared. The TiO(2) film deposited on Ti substrate obviously could not adsorb methyl orange on its surface and the titanium substrate had very weak activity under UV light irradiation. The TiO(2) films prepared without the addition of PEG 1000 were calcinated at 450 degrees C, 500 degrees C, 550 degrees C, and 600 degrees C and the film calcinated at 500 degrees C showed the optimum photocatalytic degradation activity. The addition of PEG 1000 could promote degradation of methyl orange that can be attributed to the possible pore forming in the TiO(2) film.
