a Schematic design of the H2O2 production flow cell coupling 2e− water oxidation and 2e− oxygen reduction reactions. b Cell voltage and H2O2 Faradaic efficiency and c the amount of produced H2O2 in a flow cell at a constant cell current 150 mA (1 A cm−2Pt). The data obtained from a single experiment and the applied potential here are not iR-corrected. The ohmic resistance of the flow cell was 4 ± 1 Ω.
