Schematic representation of a closed redox system for solar-driven simultaneous proton reduction and alcohol oxidation in aqueous solution. Irradiation of surface functionalized carbon nitride, NCNCNx, results in the formation of a photoexcited state in which the holes are quenched by alcohol for aldehyde formation and the photoexcited electrons are effectively transferred from NCNCNx to the molecular catalyst NiP (bromide counterions omitted for clarity) resulting in H2 formation.
