Adequate　light　absorption　and　high　carrier　separation/transfer　efficiency　are　central　to　elevate　the　development　of　highly　efficient　photocatalytic　hydrogen　evolution.　Herein,　a　unique　nano　heterostructure　is　constructed　by　translocating　0D　CdSe@(Zn,　Cd)Se@ZnS　quantum　dots　(CSS　QDs)　into　the　3D　hollow　spherical　graphite　carbon　nitride　(SCN).　The　ultrafast　TA　spectroscopy　and　electrochemical　measurements　were　measured　to　reveal　the　enhanced　surface　dependent　electron　transfer　efficiency.　Besides,　the　density　functional　theory　(DFT)　calculations　further　explained　the　mechanism　of　electrons　transfer　between　interfaces.　As　expected,　benefiting　from　the　structural　advantages　of　SCN　and　the　channel　driven　effectiveness　produced　by　a　step-accelerated　system　which　is　composed　of　(Zn,　Cd)Se　and　ZnS　double-shell　layers　of　CSS　QDs,　the　optimal　hydrogen　evolution　rate　of　the　prepared　material　in　the　photocatalytic　hydrogen　evolution　reaction　reached　132.5　mmol　h(-1),　which　was　7.6　times　higher　than　that　of　the　pure　SCN　under　visible　light　irradiation.　This　work　provides　a　novel　avenue　into　the　construction　of　nano　heterostructure　for　solar　hydrogen　evolution.　(C)　2021　Hydrogen　Energy　Publications　LLC.　Published　by　Elsevier　Ltd.　All　rights　reserved.
