Abstract：

Z-scheme　Ag3PO4/Ag/MoO3-x　photocatalyst　was　prepared　by　deposition　of　Ag　and　Ag3PO4　nanoparticles　on　the　surface　of　MoO3-x　nanosheets.　With　Ag　mediation　between　Ag3PO4　and　MoO3-x,　there　is　efficient　separation　and　utilization　of　photogenerated　charge　carriers.　Owing　to　the　rich　presence　of　oxygen　vacancies　on　the　surface　of　MoO3-x,　oxygen　adsorption　on　the　surface　is　enhanced.　The　as-prepared　Ag3PO4/Ag/MoO3-x　Z-scheme　system　shows　outstanding　photocatalytic　activity　and　stability　for　the　degradation　of　dyes　(rhodamine　B,　methylene　blue,　as　well　as　their　mixture)　and　ciprofloxacin　under　visible　light　irradiation,　displaying　degradation　rate　that　is　15.9,　3.4,　14.9　and　3.0　times　that　of　MoO3-x,　Ag3PO4,　Ag/MoO3-x　and　Ag3PO4/MoO3-x,　respectively.　According　to　the　results　of　trapping　experiments,　·OH　and　·O2−　are　the　main　active　species,　and　a　possible　reaction　mechanism　has　been　proposed.　©　2020　Elsevier　B.V.
