Abstract：

Photocatalytic　water　splitting　emerges　as　a　transformative　technology　for　sustainable　hydrogen　energy　production.　However,　reliance　on　sacrificial　hole　scavengers　(e.g.,　triethanolamine)　in　conventional　systems　leads　to　significant　underutilization　of　oxidative　potential　and　increases　the　cost　of　hydrogen　production.　Coupling　photocatalytic　hydrogen　evolution　with　the　oxidative　valorization　of　biomass-derived　polyols　establishes　a　dual-functional　system　that　simultaneously　enhances　solar　energy　conversion　efficiency　and　creates　economic　value　through　the　coproduction　of　high-value-added　chemicals.　In　this　study,　the　energy　band　structure　and　charge　carrier　behaviors　of　poly　(heptazine　imides)　are　modulated　by　salt-melt　polymerization　in　the　presence　of　different　gas　flow　atmospheres　(e.g.,　NH3,　CO2,　N2).　Accordingly,　the　optimum　potassium　poly　(heptazine　imide)　synthesized　in　the　presence　of　CO2　presents　excellent　performance　for　visible-light　photocatalytic　hydrogen　production　(apparent　quantum　yield(AQY) = 44%　under　λ = 420　nm)　coupled　with　glycerol　valorization　for　selective　synthesis　of　dihydroxyacetone　(DHA,　∼　146　µmol　of　DHA　per　hour).　This　study　provides　new　insights　into　the　rational　design　of　carbon　nitride　photocatalysts,　as　well　as　the　concurrent　achievement　of　hydrogen　evolution　coupled　with　the　production　of　high-value-added　chemicals.　©　2025　Wiley-VCH　GmbH.
