Acceptorless　photocatalytic　dehydrogenation　is　not　only　a　promising　alternative　to　photocatalytic　water　splitting　for　hydrogen　generation　but　also　provides　a　green　and　sustainable　strategy　for　the　synthesis　of　value-added　organic　compounds.　In　this　work,　Ti3C2Tx/CdS　nanocomposites　were　obtained　by　self-assembly　of　hexagonal　CdS　in　the　presence　of　preformed　Ti3C2Tx　nanosheets,　which　serves　as　a　photocatalyst　for　acceptorless　dehydrogenation　of　biomass-derived　furfuryl　alcohol　(FOL)　to　furfural　(FAL)　and　furoic　acid　(FA)　in　neutral　and　alkaline　medium　respectively,　with　simultaneous　generation　of　stoichiometric　hydrogen　under　visible　light.　Ti3C2Tx　MXene　acts　as　an　efficient　cocatalyst　for　the　photocatalytic　dehydrogenation　of　FOL　over　CdS,　with　an　optimum　performance　achieved　over　0.50　wt%Ti3C2Tx/CdS　nanocomposite.　This　study　provides　an　economic　and　sustainable　strategy　for　the　simultaneous　valorization　of　biomass-derived　FOL　to　produce　FAL　and　FA　as　well　as　the　production　of　clean　energy　hydrogen　under　mild　condition　based　on　noble　metal-free　semiconductor-based　photocatalysts.　©　2021　Wiley-VCH　GmbH
