Abstract： |
This invention discloses a TiO2 film with high light catalytic activity under visible light and its preparation method. Li and Sb salt are added in TiO2 sol by sol-gel method to get TiO3 film with high catalytic activity. This invention provides a method for preparing TiO2 film with high light catalytic activity characterizing in reducing transformation temperature of TiO2 film and getting high catalytic degradation efficiency of methy1 orange decomposition as high as 32%-67% under visible light. |
