Abstract: MoS₂/Ni₃S₂@NF hybrid catalysts were synthesized by a facile hydrothermal method for efficient alkaline oxydrogen evolution reaction (OER), which using nickel foam (NF) as both catalyst support and nickel source. The phase analysis and microstructure characterization of the electrodes were carried out by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The core-shell heterogeneous MoS₂/Ni₃S₂ junction with rough surface were uniformly and tightly distributed on NF. The electrocatalytic performance for OER performance of electrodes were investigated in alkaline solution (1 mol·L⁻¹ KOH) by electrochemical measures, such as line sweep voltammetry (LSV), eletrochemical impednance spectroscopy (EIS), chronopotentiometry and chronoamperometry. The results showed that at a current density of 10 mA·cm⁻², MoS₂/Ni₃S₂@NF electrode presented a low overpotential of 134 mV, and its corresponding Tafel slope was 55.2 mV·dec⁻¹. Moreover, after 15 hours chronopotentiometriy test, the current density of MoS₂/Ni₃S₂@NF kept above 93.5%. Chronoamperometry of three constant current densities (300, 400, 500 mA·cm⁻²) was continuous tested for 45 hours, which suggested its excellent durability.
