dc.description.abstract | The electrochemical dynamics of a film of FeCo nanopar.t.icles were studied on a glassy ;.
carbon electrode (GCE). The film was found to be electroactive in 1 M LiCI04 containing 1: I v/v
ethylene carbonate - dimethyl carbonate electrolyte system. Cyclic voltammetric experiments
revealed a diffusion-controlled electron transfer process on the GCE/FeCo electrode surface. Further
interrogation on the electrochemical properties of the FeCo nanoelectrode in an oxygen saturated 1
M LiCI04 containing 1:1 v/v ethylene-carbonate-dimethyl carbonate revealed that the nanoelectrode
showed good response towards the electro-catalytic reduction of molecular oxygen with a Tafel:t
slope of about 120 fnV which is close to the theoretical 118 mV for a single electron transfer process
in the rate limiting step; and a transfer coefficient (a) of 0.49. The heterogeneous rate constant of | en |
