The　photoelectrochemical　(PEC)　performance　of　BiVO4　is　limited　by　poor　charge　separation　and　slow　surface　water　oxidation　kinetics.　Herein,　an　simple　and　effective　caffeic　acid-assisted　solvothermal　method　was　developed　to　grow　Fe-based　metal-organic　framework　(NH2-MIL-88B(Fe))　overlayer　onto　the　Mo-doped　BiVO4　for　efficient　PEC　water　oxidation.　The　synergistic　role　of　Fe-MOF　cocatalyst　and　Mo　dopant　resulted　in　a　3.5-fold　photocurrent　density　(1.46　mA　cm-2)　increase　in　comparison　with　bare　BiVO4　(0.46　mA　cm-2)　at　1.23　V　[vs.　reversible　hydrogen　electrode　(RHE)]　and　showed　an　obviously　negative　shift　of　the　onset　potential　(200　mV).　The　enhanced　PEC　performance　can　be　attributed　to　the　improved　charge　separation　and　injection　efficiency　with　Mo　doping　and　Fe-MOF　coating,　the　introduction　of　Fe-MOF　also　increased　the　utilization　of　visible-light　and　served　as　an　efficient　electrocatalyst　to　accelerate　the　oxygen　evolution　reaction　(OER)　kinetics.　This　work　provides　a　universal　strategy　for　constructing　semiconductor/MOFs　photoanodes　for　enhanced　photoelectrochemical　water　splitting.
