Fig. 4

a Scheme of diffusional flux toward a macroelectrode and a nanoelectrode. b Illustration of the fabrication of Co–B/Ru12 CNE nanoelectrode assemblies. c CVs of CNE-1@Co–B/Ru12 in 0.1 mol L−1 NaOH containing 0.1 mol L−1 NaNO3 at a scan rate of 50 mV s−1. d CVs of CNE-2@Co–B/Ru12 in 0.1 mol L−1 NaOH containing 0.1 mol L−1 NaNO3 at a scan rate of 50 mV s−1. The insets in c and d show the 1st CVs of the bare CNE and the corresponding nanoelectrode assemblies. e Plateau current ratio normalized by the 2nd CV scans of CNE-1@Co–B/Ru12 and CNE-2@Co–B/Ru12. The potentials in (c) and (d) are not iR-corrected due to the current being in the pA range. Source data for this figure are provided as a Source Data file.
