a Schematic diagram of B/N-onion carbon catalyst. b LSV curves of different catalysts for ORR in a flow cell (1.0 M NaOH, scan rate of 20 mV s−1, with iR compensation, compensating resistance: 3.1 ± 0.2 Ω). c The corresponding Tafel plots. d FEH2O2 of B/N-onion carbon under different potentials. e Current-time curves of B/N-onion carbon under different potentials (without iR compensation). f Stability test of B/N-onion carbon at 0.4 V vs. RHE.
