摘要

•ZnO/Bi2Sn2O7 heterojunction changed charge transfer mechanism from type II into Z-scheme by Schottky junction and SPR effect of the loaded Ag nanoparticles.•The migration behavior and photocatalytic mechanism with different heterostructures were comparatively studied.•Ag@ZnO/Bi2Sn2O7 photocatalyst with superior redox capacity exibited excellent mineralization ability.
