An EQMB Examination of Cu Surface Oxides in Borate Buffer

摘要: The oxidation and reduction of copper (Cu), either electrodeposited or vapor deposited onto quartz crystal resonators, was examined in borate/boric acid mixtures at two different pH values, comparing electrochemical measurements with mass changes. results showed that 8.8, Cu dissolution significantly influences the microbalance readings. It found that, when surface during potentiodynamic scans is limited anodic direction, first peak caused by redeposition not oxide reduction. At 10.0, minimal, signal given Comparing charge data, it reaction Cu+↔Cu formation Cu2O, while Cu2+↔Cu+ most likely involves some hydroxide.
