摘要: Abstract In this study, uniform mesoporous three–dimensional LaFeO3 with diameter of 2–3 μm was prepared by a hydrothermal process and monodispersed AgCl then decorated on the surface to form AgCl/Ag/LaFeO3 heterojunction via facile precipitation–deposition process. The effects proportions employed in preparation structural, crystallinity, areas, optical properties were systematically studied, which showed that had strong hybrid–junction structure, suitable absorption edge, many exposed sites. catalytic activity during degradation methylene blue phenol under visible light. results demonstrated more intense photocurrent response smaller resistance than both LaFeO3. enhanced photocatalytic ability attributed formation heterojunctions between LaFeO3, suppressed recombination photogenerated electron–hole pairs. Our may facilitate rational design highly efficient heterogeneous for removal organic pollution.
