A) Stripping voltammogram of a Ag NP-modified GC macro electrode (sweep rate=0.02 V s−1) and B) chronoamperogram recorded during APC experiments (E=0.3 V), anodic current spikes show oxidation of Ag NPs when impacting the WE. Experiments were performed in a solution of KCl (0.09 m) and NaC6H7O7 (0.01 m).
