a Schematic illustration of the flow-cell device. b LSV curves for Pb SA/OSC, Pb SA/OC, and OSC. The curves are manually 80% iR-compensated (R = 0.4 ± 0.1 Ω). c The accumulated H2O2 concentrations and Faradaic efficiencies of Pb SA/OSC at 200 mA cm−2. d H2O2 Faradaic efficiencies and JH2O2 of Pb SA/OSC at different current densities. Error bars in (c, d) correspond to the standard deviation of three independent measurements. e H2O2 production rate of Pb SA/OSC compared to the reported state-of-the-art electrocatalysts. f Stability test and H2O2 selectivity of the Pb SA/OSC catalyst under 50 mA cm−2, with the electrolyte refreshed every 6 h during the test. g Yield of formic acid from the oxidation of glucose by the produced and commercial H2O2 at different temperatures.
