a, c The polarization curves and b, d the relevant Tafel plots of H-Mo2C/NG, Mo2C/NG, and Pt/C in a, b 0.5 M H2SO4 and c, d 1.0 M KOH, respectively. e TOF values of H-Mo2C/NG and Mo2C/NG in 0.5 M H2SO4 and 1.0 M KOH. f The plots of the current density versus the scan rate for H-Mo2C/NG and Mo2C/NG in 1.0 M KOH. Inset is cyclic voltammetry (CV) cycles of H-Mo2C/NG. g Galvanostatic measurement of H-Mo2C/NG in 0.5 M H2SO4 and 1.0 M KOH at j = –100, –200, and –300 mA cm–2, respectively.
