Abstract：

Exploiting　solar　energy　to　photocatalyze　integrated　selective　conversion　of　bioethanol　into　fine　chemicals　and　hydrogen　(H2)　is　a　promising　avenue　in　response　to　current　energy　and　environmental　crises.　Herein,　we　have　reported　the　mild　synthesis　of　a　binary　heterostructure　of　CdS-Ti3C2Tx　MXene　(CdS-MX)　combining　one-dimensional　(1D)　CdS　nanowires　(NWs)　with　two-dimensional　(2D)　MXene　structure,　and　its　application　in　photocatalytic　coupling　redox　reaction　of　H2　evolution　and　selective　conversion　of　bioethanol　into　1,1-diethoxyethane　(DEE)　under　acidic　conditions.　The　results　reveal　that　the　synergistic　effect　of　the　intimate　interfacial　contact　and　matched　energy　level　alignment　between　electrically　conductive　2D　MXene　and　semiconductor　1D　CdS　NWs　benefits　the　separation　and　migration　of　charge　carriers.　Furthermore,　[rad]CH(OH)CH3　has　been　proven　to　be　the　pivotal　radical　intermediate　during　photoredox　process.　This　work　is　anticipated　to　stimulate　further　interest　on　rational　construction　of　MXene-semiconductor　based　composites　toward　photoredox　coupling　organic　synthesis　and　H2　evolution　in　a　sustainable　manner.　©　2020　Elsevier　B.V.
