掺铈PI/SnO2复合薄膜的制备及光催化性能
Preparation and photocatalytic properties of PI/SnO2 films doping with cerium
摘要
Abstract
The PI/SnO2 films doping with cerium were prepared on flexible polyimide (PI) substrate via di⁃rect ion exchange method. The effect of different preparation conditions on the photocatalytic properties of the composite films were studied. Furthermore, the effects of the doping amount of cerium ion and the con⁃centration of ion exchange liquid on photocatalytic performance were also studied. The films were character⁃ized by SEM, EDAX, XRD and FTIR. The photocatalytic performance of the films was evaluated by the degrada⁃tion rate of the methylene blue. The results showed that the PI/SnO2 composite films with 30% (mass frac⁃tion) cerium, 0.4 mol/L total ion exchange solution concentration and calcined at 330 ℃ for 4 h, had perfect photocatalytic performance. The methylene blue degradation rate reached 94.5% at 2 h and TOC removal rate was 75.3%. The films could be recycled and showed a good degradation performance.关键词
