Bismuth oxychloride (BiOCl)/silver (Ag)/tungsten oxide (WO₃) nanocomposite was produced by laser ablation to enhance photocatalytic performance. The ternary nanocomposite showed a superior photocatalytic activity for methylene blue (MB) degradation under visible light compared to pure BiOCl and BiOCl/Ag with degradation up to 74%, 62%, and 52 %, respectively. The addition of Ag improved the dispersibility of BiOCl and WO₃, which reduced the recombination of electron–hole pairs and can be responsible for higher photocatalytic activity.

激光烧蚀合成BiOCl/Ag/WO3纳米复合材料评价其光催化性能

通过激光烧蚀制备氯氧化铋（BiOCl）/银（Ag）/氧化钨（WO ₃）纳米复合材料以增强光催化性能。与纯 BiOCl 和 BiOCl/Ag 相比，三元纳米复合材料在可见光下表现出优异的光催化降解亚甲基蓝 (MB) 活性，降解率分别高达 74%、62% 和 52%。 Ag的添加改善了BiOCl和WO ₃的分散性，从而减少了电子空穴对的复合，从而具有更高的光催化活性。
