Electrooxidation of Methanol on the Platinum Nanoparticles Modified Platinum Electrode

For the first time,the electrooxidation of methanol was investigated on the platinum nanoparticles-modified platinum electrode using cyclic voltammetry(CV) and electrochemical impedance spectroscopy(EIS) techniques.The results demonstrated that the oxidation current of methanol was greatly enhanced due to the immobilization of platinum nanoparticles,and also indicated that the increased oxidation current was not only originated from the enhancement of electrode surface and nanoparticles of platinum had an peculiar catalysis for the methanol oxidation.
