A new type of anode(Ti/SnO2+Sb2O3/PbO2) has been studied using SEM, EDS and XRD. The lifetime and kinetic parameter were determined in the solution of 1mol.L-1' H2SO4 at 80 degreesC. The electrocatalytic activities of the electrode are compared with those of noble metals and their alloys, and interpreted by the dual barrier model. The results show that this kind of anode has good lifetime and catalytic activities.
