HER performance of Pt1/hNCNC in 0.5 mol L−1 H2SO4 solution at a scan rate of 5 mV s−1 after iR-compensation. a Polarization curves. b Tafel plots. c Overpotentials at 10 mA cm−2 and mass activities at 20 mV (vs. RHE) of the series of catalysts. The data for Pt/hCNC and commercial Pt/C (20 wt% Pt) are presented for comparison
