Electrochemical Behavior of Cobaltocene in Ionic Liquids
The electrochemical behavior of cobaltocenium has been studied in a number of room temperature aprotic ionic liquids. Well defined, diffusion controlled, anodic and cathodic peaks were found for the Cc(+)/Cc (cobaltocenium/cobaltocene) reduction/oxidation on gold, platinum and glassy carbon electrod...

| Sumario: | The electrochemical behavior of cobaltocenium has been studied in a number of room temperature aprotic ionic liquids. Well defined, diffusion controlled, anodic and cathodic peaks were found for the Cc(+)/Cc (cobaltocenium/cobaltocene) reduction/oxidation on gold, platinum and glassy carbon electrodes. Values of the peak separation parameters suggest quasireversibility or even irreversibility for the redox process. The difference between the ferrocene/ferrocenium and cobaltocenium/cobaltocene couples has been evaluated as equal to (1.350 ± 0.020) V. Values of the cobaltocenium (Cc(+)) diffusion coefficients D have been calculated on the basis of the Randles–Sevcik equation. |
