Abstract A self-supported electrode with NiSe₂ hybrid nanostructure grown on carbon fiber paper (CFP) was synthesized, for the first time, by using a two-step method combining hydrothermal process with chemical vapor deposition. The morphology, composition and phases were characterized by SEM, XRD and XPS. Moreover, the HER performance of the as-grown electrode in 0.5 mol·L^-1 H₂SO₄ was determined. The results showed that the nanowires of the precursor, Ni₂(CO₃)(OH)₂, linked during the selenization reaction. The product exhibited hybrid structure of NiSe₂ nanowires and nanoparticles (H-NiSe₂/CFP), which uniformly covered the CFP. The H-NiSe₂/CFP only required a low overpotential of 232 mV to deliver the current density of 100 mA·cm^-2, which is lower than that of the NiSe₂ nanoparticles grown on CFP (NiSe₂ NPs/CFP). Accordingly, the H-NiSe₂/CFP displayed lower Tafel slope (38.3 mV·dec^-1) and charge transfer resistance (3.2 Ω) when compared with the NiSe₂ NPs/CFP. Also, the H-NiSe₂/CFP showed larger double-layer capacitance (11.81 mF·cm^-2) and TOF value (0.284 H₂·s^-1) than those of the NiSe₂ NPs/CFP. These indicated the excellent HER performance of H-NiSe₂/CFP. Moreover, this electrode exhibited remarkable stability during 3 000 times cycles CV sweeps and 20 h testing at the fixed overpotentials.
