| Abstract: | Nano-TiO2 films were prepared by Sol-gel progress. The AFM morphology of the nano-TiO2 film was given. The RMS of the film was 2.832 nm. The composition of the TiO2 sol was given by IR. Effect of different calcination temperatures and different coats of the film on the photocatalytic activity was investigated .It was found that the TiO2 films with 8 coats calcined in 490℃ had the highest photocatalytic activity. |
