Hydrophobic nickel-poly tetrafluoroethlyene(Ni-PTFE) composite electrode has been prepared by constant current and cathodic electroplating with nickel as substrate in a PTFE suspension. The Ni-PTFE electrode was used for electrooxidation of lactic acid to pyruvic acid. The electrochemical characterizations such as polarization curve, cyclic voltammogram and electrode stability have been carried out. The current efficiency of electrooxidation of the electrode with 6.7% mass fraction PTFE coating was 34% and the conversion ratio of electrooxidation of lactic acid was 72%.
