Abstract：

Photocatalysis　technology　uses　solar　energy　to　convert　biomass-derived　alcohols,　such　as　benzyl　alcohol　(BA),　into　valuable　C[sbnd]C　coupling　products　and　producing　H2,　offering　a　sustainable　way　for　generating　high-value　chemicals　and　hydrogen　energy.　However,　existing　methods　for　the　photocatalytic　oxidation　of　BA　often　suffer　from　low　efficiency　and　poor　selectivity　due　to　complex　multi-step　reactions.　Herein,　carbon-coated　Cd0.9Zn0.1S　composite　photocatalyst　(CZS@C)　is　synthesized　by　coating　carbon　shell　on　Cd0.9Zn0.1S　(CZS)　using　glucose　hydrothermal　method.　The　carbon　shell　tailors　the　surface　properties　of　CZS,　modulates　the　distribution　and　migration　of　key　intermediates　(•CH(OH)Ph),　reduces　over-oxidation　and　promotes　C[sbnd]C　coupling.　Consequently,　the　optimized　CZS@C　enhances　photocatalytic　hydrobenzoin　(HB)　synthesis,　achieving　81.6　%　BA　conversion　and　97.3　%　selectivity　of　HB.　This　study　provides　an　insight　into　integrating　photocatalytic　selective　synthesis　of　high-value　chemicals　with　H2　production.　©　2025　Elsevier　B.V.
