Abstract: The kinetics of oxygen evolution reaction(OER)on PbO_2-Ti/MnO_2 electrode has been studied using galvanistatic technique.In terms of kinetic parameters,the reaction path of OER is proposed.The electrocataIytic activity of lead dioxide and manganese dioxide has been discussed according to the theory of molecular orbit and quantum chemistry caIculation.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.

Key words: manganese dioxide, lead dioxide, oxygen evolution reaction, electrocatalysis
