Constructing　heterostructured　nanomaterials　with　integrating　different　functional　materials　into　well-oriented　nanoarchitectures　is　an　efficacious　tactic　to　obtain　high-performance　photocatalysts.　In　this　paper,　we　fabricated　three-dimensional　ZnO-WS　2　@CdS　core-shell　nanorod　arrays　as　visible-light-driven　photocatalysts　for　efficient　photocatalytic　H　2　production.　This　unique　core-shell　heterostructure　extends　visible-light　absorption　and　provides　more　active　sites.　More　importantly,　the　ZnO-WS　2　@CdS　nanorod　arrays　build　a　beneficial　energy　level　configuration　and　spatial　structure　to　accelerate　the　generation,　separation,　and　transfer　of　the　photogenerated　electron-hole.　On　the　basis　of　the　synergistic　effects,　the　photocatalytic　H　2　rate　of　optimized　ZnO-WS　2　@CdS　nanorod　arrays　achieves　15.12　mmol　h　-1　g　-1　in　visible　light　irradiation,　which　is　39,　9,　and　8　times　higher　than　pure　CdS,　ZnO-CdS,　and　CdS-WS　2　photocatalysts.　The　apparent　quantum　yield　is　up　to　14.92%　at　420　nm.　Moreover,　the　core-shell　heterostructure　photocatalyst　can　recycle　and　maintain　stability.　©　2018　American　Chemical　Society.
