BiOCl/BiOI composites with a visible light response were prepared by a simple hydrothermal method. Even though both single BiOCl and BiOI show low photocatalytic activity, BiOCl/BiOI composites provide enhanced efficiency in decomposing organic compounds including Methyl Orange (MO) and Rhodamine B (RhB). Furthermore, the 20%BiOCl/BiOI composite shows the highest efficiency for decomposing MO, while the highest performance is observed for the degradation of RhB over 70%BiOCl/BiOI composite. A possible photocatalytic mechanism has been proposed based on the relative experiments and the band positions of BiOCl and BiOI.
采用简单的水热法制备了具有可见光响应的 BiOCl/BiOI 复合材料。尽管单一组分的 BiOCl 和 BiOI 的光催化活性都较低，但 BiOCl/BiOI 复合材料在分解包括甲基橙（MO）和罗丹明 B（RhB）在内的有机化合物方面表现出了更高的效率。此外，20%BiOCl/BiOI 复合材料对 MO 的分解效率最高，而在降解 RhB 方面，70%BiOCl/BiOI 复合材料表现出了最高的性能。基于相关实验和 BiOCl 和 BiOI 的能带位置，提出了一种可能的光催化机制。
