Abstract
BiOI/TiO2/CS composite membrane materials were prepared by a simple room-temperature stirring-casting method. The BiOI/TiO2 grafted chitosan (CS) membranes exhibited enhanced visible light absorption, and their charge separation and interfacial transport were significantly improved. CS as the membrane substrate supported BiOI/TiO2/CS facilitates the recycling of the materials. The BiOI/TiO2/CS composites demonstrated enhanced photocatalytic performance for the degradation of tetracycline (TC) under UV–vis light. The composite BiOI/TiO2/CS-2 (BTC-2) was the best photocatalytic performance, completely degrading 10 ppm of tetracycline within 120 min and have good reusability. Besides, the mechanism of the enhanced photocatalytic activity of BiOI/TiO2/CS was explored.
