摘要：
Polyaniline (PAn) sensitized nanocrystalline TiOcomposites (TiO/PAn) were successfully prepared and used as an efficient photocatalyst for the degradation of dye methylene blue (MB).The results showed that PAn was able to sensitize TiOefficiently and the composite photocatalyst could be activated by absorbing both the ultraviolet and visible light (λ:190～800nm),whereas pure TiOabsorbed ultraviolet light only (λ<380nm).Under the irradiation of natural light,MB could be degraded more efficiently on the TiO/PAn composites than on the TiO.Furthermore,it could be easily separated from the solution by simple sedimentation.
