Hi All,
I am electrochemically depositing Cu using potentiostatic reduction of a Cu electrolyte (0.01M CuSO4, 0.5M (NH4)2SO4) on glassy carbon (Counter electrode is Pt wire). However on deposition at -0.3V (as identified using CV) the coating is non-uniform and disappears (due to oxidation or solvation). Does anyone have a solution?
