Selective　and　efficient　photocatalytic　transformation　of　biomass-derived　platform　molecules　to　high-value-added　fuels　or　chemicals　is　a　great　challenge　for　green　chemistry,　especially　utilizing　visible　light　energy　and　earth-abundant　catalytic　materials.　In　this　work,　we　report　a　1D/2D　MnxCd1-xS/Ti3C2　(MCSTC-X)　Schottky　junction　structure　to　achieve　efficient　photocharge　separation/transfer　via　in-situ　interfacial　self-assembly　strategy.　Under　visible　light　illumination,　the　optimized　MCSTC-7.5　catalyst　enables　the　selective　conversion　of　furfuryl　alcohol　into　furfural　with　a　production　rate　of　764.3　mu　mol　center　dot　g-　1　center　dot　h-1,　accompanied　by　water　splitting　into　H2　with　a　generation　rate　of　756.5　mu　mol　center　dot　g-　1　center　dot　h-1.　Benefiting　from　the　internal　electric　field　in　the　Schottky　junction　structure,　the　efficient　separation　and　transfer　of　photoinduced　charge　carriers　are　realized　in　one　photoredox　cycle.　Moreover,　a　plausible　reaction　mechanism　for　the　photocatalytic　selective　valorization　of　furfuryl　alcohol　to　furfural　and　H2　evolution　is　proposed.　Hopefully,　this　work　would　open　a　new　avenue　for　sustainable　and　practical　production　of　solar　chemicals　and　fuels　by　rationally　designing　1D/2D　Schottky　junction.
