Abstract：

Constructing　low-cost　and　highly　active　photocatalysts　is　extremely　desirable　for　converting　solar　energy　into　chemical　fuels.　Herein,　we　report　a　one-dimensional　(1D)　CdS@CuS-NixP　(CCN)　core-shell　heterostructure　catalyst　for　effective　photocatalytic　hydrogen　(H2)　evolution　with　modulated　charge　transfer,　which　exhibits　remarkably　higher　activity　than　bare　CdS　nanowires　(NWs).　The　evenly　distributed　and　closely　contacted　CdS@CuS　(CC)　heteroepitaxial　nanomaterial　constructs　a　type-I　heterostructure　for　improved　photoinduced　charge　carrier　separation.　The　NixP　nanoparticles　(NPs),　which　act　as　a　cocatalyst,　not　only　contribute　to　constructing　three-level　charge　transfer　by　capturing　the　photogenerated　electrons,　but　also　provide　active　sites　for　proton　reduction.　In　addition,　the　cocatalyst　strategy　reported　here　can　be　extended　to　other　transition　metal　phosphide　(TMP).　Mechanistic　studies　suggest　that　the　cooperative　synergy　of　three-level　charge　transfer　and　introduction　of　reaction　sites　results　in　a　significant　enhancement　of　photoactivity　for　H2　evolution.　©　2019　Elsevier　B.V.
