Background:　Energy　shortages　and　environmental　pollution　are　two　of　the　most　immediate　problems　all　over　the　world.　Photocatalysis　is　expanding　into　energy　and　environmental　applications.　Methods:　In　this　study,　novel　visible-light-driven　Ag2WO4/AgVO3　composite　photocatalysts　were　constructed　via　a　one-pot,　controllable,　ligand-free　and　eco-friendly　approach　and　analyzed　using　different　techniques.　Under　visible　light　irradiation,　photocatalytic　behavior　of　type-II　heterojunctions　in　the　degradation　of　levofloxacin　hydrochloride　is　investigated.　Significant　findings:　Various　characterizations　showed　that　Ag2WO4　was　successfully　loaded　onto　the　AgVO3　surface,　which　improved　the　separation　and　transfer　efficiency　of　the　photogenerated　charge　carriers.　Under　optimal　experimental　conditions,　the　removal　efficiency　of　levofloxacin　reached　0.0194　min-1　for　the　Ag2WO4/AgVO3　composites　with　a　3:　5　mass　ratio　(3-WV),　which　was　5.87　and　17.64　times　that　of　pure　AgVO3　and　Ag2WO4,　respectively.　The　photocatalytic　mechanism　of　typical　type-II　heterojunction　was　discussed.　Furthermore,　possible　photodegradation　pathway　of　levofloxacin　was　comprehensively　determined　by　LC-MS　analysis.　This　work　will　provide　new　motivation　for　the　design　and　synthesis　of　simple　preparation　and　highly　efficient　photocatalysts　for　environmental　purification.　©　2024　Taiwan　Institute　of　Chemical　Engineers
