One-step electrodeposition of W, Mo-Ni₃S₂/NF catalyst: an efficient hydrogen evolution electrode for alkaline media.

ABSTRACT: A self-supported tungsten (W), molybdenum (Mo)-Ni₃S₂/nickel foam (NF) hydrogen evolution reaction (HER) electrode was successfully fabricated on NF via constant current electrodeposition. The morphology, elemental composition, and electrocatalytic HER performance of the electrodes were systematically characterized via scanning electron microscopy, transmission electron microscopy, X-ray diffraction, and an electrochemical workstation. Results indicate that the surface of the W, Mo-Ni₃S₂/NF electrode consists of rough and refined nano-spherical particles with certain amorphous characteristics. In 1 M KOH, the W, Mo-Ni₃S₂/NF electrode demonstrates superior catalytic HER activity and stability. In particular, it a
