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

Abstract

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.
