A highly efficient Ni-Fe-Sn electrocatalyst supported on nickel foam was successfully fabricated, showing low overpotential and superior stability for hydrogen evolution reaction in alkaline condition. The remarkable electrocatalytic activity was attributed to the synergistic effects between Ni, Fe, and Sn during the hydrogen evolution reaction process.
Ni-Fe-Sn electrocatalyst supported on nickel foam (Ni-Fe-Sn/NF) with high efficiency of hydrogen evolution reaction (HER) has been successfully fabricated through one-step potentiostatic electrodeposition route. The optimized Ni-Fe-Sn/NF displayed an extremely low overpotential of, respectively, 144 and 180 mV at 50 and 100 mA cm-2 for HER in alkaline condition. Moreover, it could retain its superior stability for at least 12 h. The remarkable electrocatalytic activity of our electrocatalyst is ascribed to the high conductivity originated from synergistic effects between Ni, Fe, and Sn during HER process.
