Figure 3. LSV curves of different electrodes based on (A) geometric area of electrode and (B) Pt mass loading in 0.5 M H2SO4 at a scan rate of 5 mV s-1. (C) Bar diagram for η10 at different electrodes. (D)Comparison of ECSA (left axis), current density normalized SA (right axis) and MAs (normalized by Pt mass, right axis) for HER at -70 mV for different electrodes. (E) Tafel slope for HER catalysis at different electrodes. (F) Chronopotentiometric measurements of long-term stability at -0.23 V. LSV: Linear sweep voltammetry; ECSA: electrochemical surface area; HER: hydrogen evolution reaction.
