Vanadium-Doped NiCoP Nanosheets for Enhanced Hydrogen Evolution Reaction in Alkaline Media

Abstract
Modifying the intrinsic activity and conductivity of electrocatalysts represents a pivotal approach for achieving outstanding
performance in the hydrogen evolution reaction (HER). In this study, we focused on the rational fabrication of
vanadium (V)-doped nickel cobalt phosphide on Ni foam (VNiCoP/NF) employing a wet chemical synthesis followed by
a controlled NaH2PO2-assisted solid-gas phosphidation process. Electrochemical measurements conducted in an alkaline
electrolyte demonstrated the significantly enhanced electrocatalytic activity of the synthesized VNiCoP/NF nanoparticles
for HER, achieving overpotentials of 141, 137, and 79 mV at current densities of 200, 100, and 10 mA cm−2
, respectively.
The exceptional electrocatalytic performance of the VNiCoP/NF catalyst can be ascribed to the enhanced intrinsic activity
and conductivity resulting from the phosphating process and the incorporation of vanadium, as well as the synergism
between the V and NiCoP active sites. Prominently, the VNiCoP/NF catalyst demonstrated remarkable long-term stability
for 50 h at 100 mA cm−2
. Consequently, the introduction of metal doping into phosphides based on transition metals
represents a highly promising strategy for developing exceptionally efficient HER electrocatalysts for green hydrogen
production.
