Polymeric　carbon　nitride　(PCN)　photosensitizers　are　proposed　replacements　for　their　inorganic　counterparts　in　solar-to-fuel　conversion　via　photoelectrochemical　water　splitting.　However,　intense　charge　recombination,　primarily　because　of　surface　defects,　limits　the　use　of　PCN　in　PEC　systems.　Now,　photoanodes　are　designed　by　coating　PCN　films　onto　highly　conductive　yttrium-doped　zinc　oxide　(Y:ZnO)　nanorods　(NRs)　serving　as　charge　collectors.　The　generation　of　charge　carriers　can　therefore　be　promoted　by　this　typeII　alignment.　The　charge　collectors　would　be　kept　nearby　for　charge　separation　and　transport　to　be　used　in　the　interfacial　redox　reactions.　The　photocurrent　density　of　the　polymer　electrode　is　improved　to　0.4mAcm(-2)　at　1.23V　vs.　the　reversible　hydrogen　electrode　in　a　Na2SO4　electrolyte　solution　under　AM1.5　illumination.　The　result　reveals　a　more　than　50-fold　enhancement　over　the　PCN　films　achieved　by　powder;　the　efficiency　can　be　preserved　at　95%　for　160minutes.
