In order to improve the electrical conductivity and electrocatalytic activity of the Ti/PbO2 electrode, the Ti substrates were electrodeposited with a bottom layer of the nafion-CNTs (carbon nanotubes) film. Then, doped PbO2 ?lms were electrodeposited on above substrates.The effects of pH, current intensity and electrolysis time on the degredation of phenol simulated wastewater were investigated. Furthermore, the kinetic analysis was carried out. The results showed that the conductivity of the modified electrode was enhanced and the degradation effiiency could be 46.2% as the pH solution of 6, current of 1 ampere and worked for one hour. The electric energy consumption increasesd along with the heat of reaction. The reaction accorded with the first-order kinetic equation.
