A MICROSCOPIC MODEL OF ELECTRON-TRANSFER AT ELECTROACTIVE SITES OF MOLECULAR DIMENSIONS FOR REDUCTION OF CYTOCHROME-C AT BASAL-PLANE AND EDGE-PLANE GRAPHITE-ELECTRODES

Abstract:

A microscopic model of electron transfer, which assumes that electron transfer occurs only after radial diffusion to oxygen-functionalized sites of molecular dimension in size, has been developed to explain the electrochemical reduction of horse heart cytochrome c at graphite electrodes. By use of this model, the conclusion is reached that the rate of electron transfer is greater than 1 cm s-1 at both basal- and edge-plan graphite electrodes and silanized or "aged" graphite electrodes. Accord...
