1¡¢Calculation of ECAS: The calculation of electrochemically active surface area (ECAS) is estimated from the double layer capacitance (Cdl) of the different catalysts in 1 M KOH based on the previous published report.1-3 The charging current (ic) was measured from the CVs at different scan rates, as shown in Figure S4c and Figure S13. The relation between ic, the scan rate (¦Í) and the Cdl was given in equation (1). ic = ¦ÍCdl£¬Therefore, the slope of ic as a function of ¦Í is equal to Cdl. For the calculation of ECAS, the specific capacitance (Cs) value is 0.040 mF cm-2 in 1 M KOH. So the ECAS of is calculated according to equation (2).

2¡¢Estimation of Effective Electrode Surface Area. Based on literature, cyclic voltammetry (CV) could be carried out in neutral media to probe the electrochemical double layer capacitance of various samples at non-Faradaic overpotentials as the means for estimating the effective electrode surface areas. Accordingly, a series of CV measurements were performed at various scan rates (4 mV s-1, 8 mV•S-1, 12 mV•S-1, 16 mV•S-1, etc.) in 0.104 to 0.204 V vs. RHE range, and the sweep segments of the measurements were set to 10 to ensure consistency. By plotting the difference in current density (J) between the anodic and cathodic sweeps (Janodic - Jcathodic) at 0.15 V vs. RHE against the scan rate, a linear trend was observed. The slope of the fitting line is found to be equal-to-twice the geometric double layer capacitance (Cdl), which is proportional to the effective electrode surface area of the materials. Therefore, the electrochemical surface areas of different samples can be compared with one another based on their Cdl values. However, it should be noted that this comparison makes sense only when the measurement of materials are carried out under same condition.
