• Glassy carbon
• OH radicals
• Metal nucleation
• Surface erosion

GC electrodes were exposed to Fenton solutions. The surface changes produced by the OH center dot radicals of these solution were inspected using SEM, XPS, Raman spectroscopy and electrochemistry. The OH center dot radicals caused erosion and roughening of the surface, selective oxidation and dissolution of sp(2) carbon, and reduction of the number of nucleation sites for silver deposition.
