Silver Electrodeposition from Ag/AgCl Electrodes: Implications for Nanoscience.

With the advancement of nanoscience, silver/silver chloride (Ag/AgCl) electrodes have become widely utilized in microscale and nanoscale fluidic experiments, because of their stability. However, our findings reveal that the dissolution of AgCl from the electrode in Cl-rich solutions can lead to significant silver contamination, through the formation of silver complexes, . We demonstrate the electrodeposition of silver particles on graphene in KCl aqueous solution, with AgCl dissolution from the electrode as the sole source of silver.
