文摘

Hollow Ag/AgCl/BiOCl microspheres photocatalysts have been successfully fabricated by anchoring Ag/AgCl nanoparticles on the surfaces of BiOCl microstructures. The as-synthesized composites greatly enhanced photocatalytic performance in the degradation of methyl orange under LED light irradiation, which was much higher than the Ag/AgCl or pure BiOCl. The photocatalytic mechanisms were analyzed by active species trapping experiment, where the photogenerated hole played critical roles in the reacting process. Our results revealed that the surface plasmon resonance of metallic Ag and heterojunction of Ag/AgCl/BiOCl photocatalysts had a great effect on the photocatalytic activity.
