摘　　要：采用静电自组装工艺在石英衬底上制备了SnO2掺杂的TiO2薄膜,利用原子力显微镜(AFM),X射线光电子能谱(XPS),紫外可见分光光度计(UV-Vis)表征了薄膜的微结构及性能。薄膜的吸收光谱及光催化实验结果表明,SnO2掺杂可以明显改善薄膜的光吸收,提高TiO2薄膜的光催化性能。TiO2 films doped with SnO2 were prepared on quartz substrate by electrostatic self-assembly method in this paper. Atom force microscopy (AFM), X-ray photoelectron spectroscopy (XPS) and UV-Vis-NIR spectrophotometer were employed to characterize the microstructure and performance of the samples. Results of the optical absorption spectra and the measurement of photo-catalytic activity show that the photo-absorbency of the samples is greatly increased and the photo-catalytic activity of the films is well improved by SnO2-doping.
