Ni-Mo-PTFE composite electrode was obtained from a mixture containing 0.22 mol/L NiSO₄·6H₂O, 0.06 mol/L Na₂MoO₄·2H₂O, 0.3 mol/L Na₃C₆H₅O₇·2H₂O, 30 g/L PTFE and 0.1 g/L FC-400 surfactant (pH=9) in 45℃ with current density of 10 mA/cm². XRD of the composite deposit reveals that it is a face centered cubic solid solution and exhibits (111) preferred orientation. X-ray photoelectron energy spectra of the composite deposit indicate that fluorine exists in form of (CF₂)_n. SEM showed the larger surface roughness of the electrode. The mechanism of Ni-Mo-PTFE composite electrodeposition has been discussed. The cyclic voltammetric study showed that the electrocatalytic activity of Ni-Mo-PTFE electrode on methanol oxidation is bigger than that of Ni-Mo electrode.
