Figure 1.

Representative cyclic voltammograms in the presence (colored lines) and absence (black lines) of 12 pm AgNPs in 20 mm KF, KCl, and KBr (left to right) supporting electrolytes. All measurements made at a carbon microdisc working electrode (16.5 μm radius) and a scan rate of 10 mV s⁻¹. Inlay depicts the potential range 0.2 V to 0.8 V in more detail for KBr supporting electrolyte, displaying the reduction in frequency of oxidative spikes on the backward scan.
