The　water　splitting　reaction　to　produce　hydrogen　is　one　of　the　most　promising　and　cleanest　ways　to　resolve　the　energy　crisis.　However,　the　preparation　of　efficient　and　stable　electrocatalysts　with　low-cost　remains　challenging.　In　this　work,　the　noble-metal　free　N-doped　carbon　(NC)　incorporated　V-doped　cobalt　phosphide　(CoP)　nanosheets　on　nickel　foam　(NF)　(denoted　as　V-CoP-NC/NF)　are　prepared　by　using　two-dimension　zeolitic　imidazolate　framework　(ZIF-67)　as　precursor　followed　by　NaVO3　etching/doping　and　phosphorization.　The　V　doping　is　found　to　be　essential　to　enhance　the　electrochemical　performance　of　CoP　for　water　splitting.　In　particular,　V5-CoP-NC/NF　(V5　represents　the　concentration　of　NaVO3　for　etching/doping　is　5　mM)　exhibits　the　highest　hydrogen　evolution　performance　in　alkaline　electrolyte,　to　achieve　a　current　density　of　10　mA　cm−2,　an　overpotential　of　119　mV　(vs　reversible　hydrogen　electrode)　is　required.　X-ray　photoelectron　spectroscopy　results　show　that　the　V　doping　significantly　altered　the　binding　energies　of　Co　2p,　P　2p　and　N　1　s　in　V5-CoP-NC/NF,　which　is　believed　to　facilitate　the　adsorption　and　dissociation　of　intermediates　and　accelerate　interfacial　charge　transfer　during　hydrogen　evolution　reaction　process.　This　work　provides　a　simple　route　to　prepare　heteroatom　doped　CoP　self-standing　electrocatalysts　for　water　splitting.　©　2023
