摘要

通过激光烧蚀法制备了氧氯化铋（BiOCl）/银（Ag）/氧化钨（WO3）纳米复合材料，以提高其光催化性能。与纯 BiOCl 和 BiOCl/Ag 相比，三元纳米复合材料在可见光下降解亚甲基蓝（MB）的光催化活性更优，降解率分别高达 74%、62% 和 52%。添加 Ag 提高了 BiOCl 和 WO3 的分散性，从而减少了电子-空穴对的重组，这可能是提高光催化活性的原因。

Laser ablation synthesis of BiOCl/Ag/WO3 nanocomposite to evaluate its photocatalysis performance

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.
