Fig. 4

a LSV plots of Cu NWs and OD-Cu NWs in argon saturated 1 M KOH aqueous solutions with or without the addition of AN (8 wt%). The scan rate was 10 mV s−1. b FEEA and current densities with different potentials on Cu NWs and OD-Cu NWs. c MEA device diagram. d AEM-MEA test of FEEA at different high currents in OD-Cu NWs. e Long-term durability and corresponding FEEA of OD-Cu NWs using AEM-MEA at a constant current of 1.6 A (in a 1 M KOH electrolyte containing 8 wt% AN). The error bars represent Fig. 4b based on triplicate measurements.
