Abstract：

The　application　of　cadmium　sulfide　is　severely　limited　by　photo-corrosion　and　electron-hole　recombination.　In　this　work,　hierarchically　structured　Zr-based　UiO-67　assembled　from　ultrathin　nanosheets　was　rapidly　synthesized　by　microwave　and　treated　as　support　to　disperse　CdS　and　Pt　NPs.　Owing　to　the　intimate　interfacial　contact　between　CdS　and　UiO-67,　synthesized　CdS/Pt/UiO-67　composites　exhibit　higher　activity　of　hydrogen　evolution　than　that　of　pure　CdS　under　visible　light　irradiation.　Femtosecond　transient　absorption　spectra　has　been　utilized　to　reveal　the　charge　separation　kinetics　in　CdS/Pt/UiO-67.　In　CdS/Pt/UiO-67　composites,　MOF　is　not　only　used　as　support　to　disperse　CdS,　but　also　acted　as　electron　trapping　agent　to　reduce　the　recombination　of　photogenerated　electrons　and　holes.　This　work　makes　us　have　a　deeper　understanding　of　the　charge　transfer　between　semiconductor　and　MOF　materials.　©　2022　Elsevier　Ltd.　All　rights　reserved.
