Black BiOCl with oxygen vacancies was prepared by UV light irradiation with Ar blowing. The as-prepared black BiOCl sample showed 20 times higher visible light photocatalytic activity than white BiOCl for RhB degradation. The trapping experiment showed that the superoxide radical (O(2)(•-)) and holes (h(+)) were the main active species in aqueous solution under visible light irradiation.
采用 Ar 气吹扫的紫外光照射法制备了具有氧空位的黑色 BiOCl。所制备的黑色 BiOCl 样品在可见光照射下对 RhB 的降解表现出比白色 BiOCl 高 20 倍的光催化活性。捕获实验表明，在可见光照射下，超氧自由基（O(2)(•-))和空穴（h(+))是水溶液中的主要活性物种。
