Abstract:
Here we demonstrate the improvement of the intrinsic electrocatalytic hydrogen evolution activity of NiPS3 by proper cobalt doping. The optimized Ni0.95Co0.05PS3 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.
