Study of oxygen reduction on copper applied to the peroxidase-mediated oxidation of methylene blue
The kinetics of oxygen reduction was studied on copper in tartarate solutions using a rotating disc electrode. The effect of pH on the cathodic reduction was examined. AC impedance and cathodic polarization curves showed that the reaction is partially controlled by mass transport. At high current de...
