چکیده
|
The electro-reduction of oxygen on silver-modified glassy carbon electrode(ag/gc) in acidic solution at different potentials was studied by ac-impedance spectroscopy.the influence of the electrode potential on impedance of oxygen reduction reaction is studiedand a mathematical model was put forward to quantitative account for the impedancebehavior of oxygen reduction. at potentials higher than -0.4 v/ag-agcl, a pseudo-inductivebehavior is observed. the conditions required for this behavior are delineated with the use ofthe impedance model.
