a HER polarization curves for Pt/C60-2/KB, C60/Pt(dba)2/KB, Pt/C, and KB in 1 M KOH. b Tafel plots derived from the corresponding polarization curves. c Nyquist plots for Pt/C60-2/KB, C60/Pt(dba)2/KB, and Pt/C at an overpotential of 1.5 V (vs RHE) (The system resistance is 2.5 Ω and 2.6 Ω for Pt/C60-2/KB and Pt/C measurements, respectively). d Capacitive Δ j = ja − jc as a function of scan rate in 1 M KOH. e TOF values for Pt/C60-2/KB, Pt/C and other reported electrocatalysts over a wide range of overpotentials. f LSV curves for Pt/C60-2/KB and Pt/C before and after 3000 catalytic cycles in 1 M KOH. g Long-term stability test at a current density of 10 mA cm−2 in 1 M KOH. h HER polarization curves for Pt/C60-2/KB and Pt/C under multiple loadings in 1 M KOH. i LSV curves for Pt/C60-2/KB and Pt/C before and after 3000 catalytic cycles in 5 M KOH at 60°C (LSV curves are with 90% iR correction. Non-iR corrected data for Fig. 5a, h, i is provided as Supplementary Fig. 11).
