a HER polarization curves of CNT, Mo2C@CNT, Ru@CNT, Pt/C, and Ru-Mo2C@CNT catalysts. b Tafel plots obtained from the polarization curves in a. c Comparison of overpotential changes at 10 mA cm−2 and exchange current density. d In 1.0 M KOH solution, compared with the recently reported HER catalyst Tafel slope and overpotential at 10 mA cm−2. e The potential-dependent TOF curves of Mo2C@CNT, Ru@CNT, Pt/C, and Ru-Mo2C@CNT. f Polarization curves for Mo2C@CNT, Ru@CNT, Pt/C, and Ru-Mo2C@CNT catalysts before and after 10,000 cycles.
