Criteria for the selection of the scan rate in the evaluation of the kinetic parameters of the hydrogen oxidation reaction by a potentiodynamic sweep

The use of the current density values obtained from a voltammetric sweep at a slow scan rate jvs(η) in place of those of a steady state polarization jss(η) for the determination of the kinetic parameters of the hydrogen oxidation reaction (hor) on a rotating disc electrode was analyzed. Three sets o...
