Designing　low-content　and　high-activity　Pt-based　catalysts　with　the　high　durability　for　the　electrochemical　hydrogen　production　remains　a　challenge.　In　this　study,　a　ternary　metal　phosphide　(NiCoP)　with　1D　nanowire　(NW)　and　2D　nanosheet　(NS)　morphologies　incorporating　Pt　clusters　(denoted　as　Ptcluster-NiCoP@NF　NWs　and　Ptcluster-NiCoP@NF　NSs,　respectively)　was　prepared　using　a　hydrothermal–phosphorization–electrodeposition　method.　Based　on　the　“tip　effect”　of　NWs　and　a　high　electrochemical　surface　area,　the　as-prepared　Ptcluster-NiCoP@NF　NWs　display　better　hydrogen　evolution　reaction　(HER)　performance,　with　a　low　overpotential　of　65　mV　at　a　high　current　density　of　100　mA　cm−2　and　a　low　Tafel　slope　of　38.86　mV　dec−1,　than　the　Ptcluster-NiCoP@NF　NSs,　with　an　overportential　of　95　mV　at　42.53　mV　dec−1.　This　indicates　that　the　NiCoP　NW-based　support　exhibits　faster　HER　kinetics.　The　mass　activity　(11.47　A　mgPt−1)　of　the　Ptcluster-NiCoP@NF　NWs　is　higher　than　that　of　commercial　Pt/C　catalysts.　Significantly,　the　Ptcluster-NiCoP@NF　NWs　display　excellent　cyclic　stability　with　negligible　losses　for　5000　cycles　and　30-h　tests　at　a　high　current　of　500　mA　cm−2.　©　2024　Elsevier　Inc.
