Abstract：

The　development　of　copolymerized　carbon　nitride　(CN)-based　photocatalysts　may　support　advances　in　photocatalytic　overall　water　splitting.　However,　the　recombination　of　charge　carriers　is　the　main　bottleneck　that　reduces　its　overall　photocatalytic　activity.　To　overcome　this　problem,　the　construction　of　heterojunction　technology　has　emerged　as　an　effective　approach　to　reduce　the　charge　carrier　recombination,　thereby　improving　charge　separation　and　transport　efficiency.　In　this　work,　an　innovative　heterojunction　was　prepared　between　Quinolinic　acid　(QA)　modified　CN　(CN-QAx)　and　novel　nanorod-shaped　bismuth　vanadate　(BiVO4)　(BiVO4/CN-QAx)　for　overall　water　splitting　through　a　simple　in-situ　solvent　evaporation　technique.　The　obtained　results　show　that　the　synthesized　samples　have　efficient　and　improved　activities　for　releasing　H2　(862.1　μmol/h)　and　O2　(31.58　μmol/h)　under　visible　light　irradiation.　Furthermore,　an　exceptional　apparent　quantum　yield　(AQY)　of　64.52　%　has　been　recorded　for　BiVO4/CN-QA7.0　at　420　nm,　which　might　be　due　to　the　substantial　isolation　of　photoinduced　charge　carriers.　Therefore,　this　work　opens　up　a　new　channel　toward　efficient　CN-based　photocatalysts　in　the　sustainable　energy　production　processes.　©　2022　Elsevier　Inc.
