Popis:	TiO2 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 TiO2 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 TiO2 films prepared without the addition of PEG1000 were calcinated at 450 oC, 500 oC, 550 oC, and 600 oC and the film calcinated at 500 oC showed the optimum photocatalytic degradation activity. The addition of PEG1000 could promote degradation of methyl orange that can be attributed to the possible pore forming in the TiO2 film.
