a H2O2 selectivity of CNT, 0SCNT, 0.4SCNT and 0.9SCNT in 0.1 M K2SO4. Their H2O2 concentrations (mM) and FEsH2O2 in 0.1 M K2SO4 (b), KOH (c), and H2SO4 (d) at 1.0 A cm−2. H2O2 concentrations (mM) and FEsH2O2 of 0.9SCNT in 0.1 M K2SO4 (e) and KOH (f) at 0.1–1.5 A cm−2. g Its FEsH2O2 in 0.1 M H2SO4 and 0.1 M H2SO4 + 0.1 M K2SO4 at 0.1–1.5 A cm−2. h Comparison of FEsH2O2 and H2O2 yields between 0.9SCNT and other reported electrocatalysts. Error bars represent the standard deviation from three independent measurements. All the potentials have not been iR-corrected. Source data for the figure are provided as a Source data file.
