Precise　regulation　and　control　solar-light-driven　charges　photoexcited　on　photocatalysts　for　separation-transfer　and　target　redox　reactions　is　an　attractive　and　challenging　pathway　toward　sustainability.　Herein,　0D/2D-3D　Pt/In2S3　Schottky　junction　was　fabricated　for　simultaneous　selective　phenylcarbinol　conversion　into　value-added　aldehydes　and　production　of　clean　energy　H-2　by　directly　utilizing　photoexcited　holes　and　electrons　in　one　reaction　system　under　mild　reaction　conditions.　In　contrast　to　pure　water　splitting　and　pure　In2S3,　the　reaction　thermodynamics　and　kinetics　of　H-2　evolution　on　the　Pt/In2S3　were　significantly　enhanced.　The　optimized　0.3%　Pt/In2S3　exhibited　the　highest　and　most　stable　photocatalytic　activity　with　22.1　mmol　g(-1)　h(-1)　of　H-2　production　rate　and　almost　100%　selectivity　of　benzaldehyde　production.　Notably,　this　dual-function　photocatalysis　also　exhibited　superiority　in　contrast　to　sacrificial-agent　H-2　evolution　reactions　such　as　lactic　acid,　Na2S,　methanol　and　triethanolamine.　The　turnover　frequency　(TOF)　could　reach　up　to　similar　to　2394　h(-1).　The　Pt　clusters　anchored　at　the　electron　location　and　strong　metal-support　interactions　(SMSI)　between　Pt　and　In2S3　synergistically　improved　the　spatial　charge　separation　and　directional　transportation　(similar　to　90.1%　of　the　charge　transport　efficiency　could　be　achieved　over　the　Pt/In2S3　hybrid),　and　thus　result　in　significant　enhancement　of　photocatalytic　H-2　evolution　with　simultaneous　benzaldehyde　production.
