a, b LSV curves for 2e- ORR in 1.0 M KOH and 1.0 M Na2SO4 electrolytes with 80% iR-Compensation (0.84 ± 0.09 Ω for 1.0 M KOH and 3.13 ± 0.13 Ω for 1.0 M Na2SO4). Corresponding FEs and production rates of H2O2 under different current densities are shown. The LSV curves were measured three times in Supplementary Fig. 29. c, d 140-hour stability test for Bn-C at 300 mA cm−2 in 1.0 M KOH at 0.42 V vs. RHE and in 1.0 M Na2SO4 at 0.10 V vs. RHE, respectively. e Performance comparison of catalysts in a flow cell in terms of durability, FE and yield rate (Supplementary Table 4).
