From: Boosting hydrogen evolution on MoS2 via co-confining selenium in surface and cobalt in inner layer
a HER polarization curves for the Se-MoS2-NF with different Se doping contents in comparison with those of bulk MoS2, MoS2-NF, and 40% Pt/C. b Variation of the overpotentials depending on the Se doping content at current densities of 10, 50, and 100 mA cm−2, respectively. All catalysts are drop-casted on glassy carbon electrode for HER measurements, which were conducted in a 0.5 M H2SO4 electrolyte at 25 °C.
