| Abstract: | In this paper,equations for chronoamperometric current and linear sweep voltammetry are derived for the case where the EC'catalytic reation occurs at an electrode with finite linear diffusion space.The analytical expression for chronoamperometric current is given and voltammogram is obtained by numerical calculation.The voltammogram varies with both the kinetic parameter,P=kfCZF*d2/D, and the scan rate parameter,w=nFvd2/RTD,where the kf is the rate constant of the catalytic reaction,CZF is the bulk concentration of catalyst in film,d is the thick of film,v is the potential sweep rate.Others have the normal meaning.The dependence of the current potential curves on these two parameters is discussed.From this dependence,a concept of quasi-steady-state catalytic current is developed. |
