a Polarization curves of a Ta foil, Ta-TaS2 MC, Ta/TaS2 and a porous Pt foil measured in a 0.5 M H2SO4 electrolyte with a scan rate of 2 mV s−1. b Δη/Δlog| j| ratios of the Ta-TaS2 MC, Ta/TaS2 and porous Pt foil catalysts at different current densities. c HER activity of the Ta-TaS2 MC and Ta/TaS2. d i-t curves of the Ta-TaS2 MC at various current densities in a 0.5 M H2SO4 electrolyte. e Comprehensive comparisons of the HER performance of Ta-TaS2 MC with those reported state-of-the-art catalysts in literature. From left to right: the largest test current; the current density @η = 300 mV; current density for stability test; stability test time.
