While electrochemically cleaning gold disk electrode (2mm), observe reduction around 0.7 V in addition that of 0.9 V vs Ag/AgCl reference electrode ?

25 September 2024 0 5K Report

When I electrochemically clean the Au disk electrode of diameter 2mm in 0.1 M sulphuric acid, I observed the reduction peak at 0.75 V in addition to that of Au-O reduction peak around 0.9 V vs Ag/AgCl (3M KCl) reference electrode.

Is it advisable to use GC (3mm diameter) as a counter electrode for the above treatment?
