| 中文摘要 | reduction of hydrogen peroxide at a glassy carbon (gc) electrode modified with sigma-bonded pyrrole iron(iii) octaethylporphyrin complex, (oep)fe(pyr), was studied by cyclic voltammetry and a rotating disk electrode. in 0.1n naoh solution, it is shown that such an (oep)fe(pyr)/gc electrode has a significant catalytic activity towards hydrogen peroxide reduction (e(d) = -0.80 v, k = 0.066 cm s(-1)); however, the electrode stability is low. the deactivation is observed when the reaction charge (q) is passing through the (oep)fe(pyr)/gc disk electrode. a linear rotation scan method is applied to study the kinetic process by determining the disk electrochemical response (i(d)) to rotation rate (omega) at a definite disk potential (e(d)). considering that the number of adsorbed electroreduced catalyst molecules (red) varies according to the disk potential, a factor theta(= gamma(red)/(gamma(red) + gamma(ox))) is introduced to describe the electrode surface area fraction for electroreduced species. the obtained koutecky-levich equation is applicable whatever the potential is. |
