Theoretical and experimental studies of periodic currents and potentials in electroplating and in fast kinetics on a rotating disk electrode
Abstract
A systematic investigation of mass transfer rates to a rotating disk electrode under periodic currents and potentials is presented. Included are: (1) A numerical solution was obtained for mass transfer to a rotating disk electrode under pulsed current conditions; (2) A method based on a combination of pulsed electrolysis and stirring was developed to study fast electrode reactions; (3) A general solution was derived for the mass transfer to a rotating disk electrode under periodic currents; (4) A numerical solution was presented to calculate the instantaneous current density under pulsed potential conditions for intermediate and large cycle times; (5) The calculation of the maximum electrolysis rates under intermittent potential conditions was discussed; and (6) A calculation was made on the current efficiencies when two competing but irreversible reactions take place at the electrode surface under pulsed current conditions.
