KINETICS OF OXYGEN EVOLUTION REACTION ON PbO_2-Ti/MNO_2 ELECTRODE AND THE ELECTROCATALYSIS
PbO2—Ti／MnO2电极上析氧反应动力学及电催化

The kinetics of oxygen evolution reaction (OER) on PbO_2--Ti/ MnO_2 elec-trode has been studied using galvanistatic technique. In terms of kinetic parameters, the reac-tion path of OER is proposed. The electrocatalytic activity of lead dioxide and manganese dioxide has been discussed according to the theory of molecular orbit and quantum chemistry calculation. It is concluded that the electrocatalytic activity of manganese dioxide is higher than that of lead dioxid, which is in agreement with the experimental result.
