Abstract

Here we demonstrate the improvement of the intrinsic electrocatalytic hydrogen evolution activity of NiPS₃ by proper cobalt doping. The optimized Ni_0.95Co_0.05PS₃ nanosheets display a geometric catalytic current density of -10 mA cm^-2 at an overpotential of 71 mV vs. RHE and a Tafel slope of 77 mV dec^-1 in 1.0 M KOH.
