(a) Cyclic voltammetry of Ag electrode (1.6 mm diameter disk) in 0.1 M NaOH electrolyte. Solid: N2 purge, dotted: H2 purge, and dashed: O2 purge. Voltammograms were conducted under saturated conditions at 50 mV/sec over a voltage range of 0.0–1.4 V versus RHE. (b) Cyclic voltammetry of Ag electrode (1.6 mm diameter disk) in 0.1 M NaOH electrolyte. Solid: N2 purge, dotted: xM H2O2 with N2 purge, and dashed: 10 xM H2O2 with N2 purge. Exact concentrations were unknown due to H2O2 degradation, but were on the order of 1 mM and 10 mM H2O2. Scans were conducted under saturated conditions at 50 mV/sec over a voltage range of 0.0–1.4 V versus RHE.
