a Polarization curves (solid lines) at a rotation of 1600 rpm for NiBDC and B-NiBDC, and simultaneous H2O2 detection currents on the ring electrode (dashed lines) at 1.2 V vs. RHE in O2-saturated 0.1 M KOH electrolyte (solution resistance = 55.8 ± 3.2 Ω). b Calculated H2O2 selectivity (%) and electron transfer number (n). c Tafel slopes of NiBDC and B-NiBDC. d Illustration of gas diffusion electrode (GDE) in a three-phase flow cell set-up for H2O2 production. e Polarization curves and f corresponding H2O2 FEs of NiBDC and B-NiBDC in a flow cell using 1.0 M KOH as electrolyte (solution resistance = 2.6 ± 0.4 Ω). Error bars correspond to the standard deviation of the three measurements. g Chronopotentiometric curves at 1000 mA cm-2 for B-NiBDC and the corresponding H2O2 FEs.
