Synergistic Effect of the Oxidation of Formic Acid at Polyaniline Electrodes Modified by Palladium Microparticles
【Abstract】 Electrochemical oxidation of formic acid on PAN(Pd) electrode has been studied using conventional electrochemical tecdriques and the electrochemical in-situ FTIR.The process of electrochemical oxidation of PAN(Pd) electorde has been put forward. The kinetic parameters of different thickness of PAN film such as diffision coefficient (D0) and reaction rate constant(k0) have been calculated. Furthermore, the causes of the difference between PAN(Pd) and pure Pd(or Pt) electrodes as well as the high electrocatalytic activation of PAN(Pd) electrode for oxidation of fomic acid have also been discussed. The high catalytic activation of PAN(Pd) electrode for oxidation of formic acid probably comes from the synergistic effect of the subcatalytic interaction of PAN and the catalytic interaction of the palladium microparticles.
