| Abstract: | The Pt/GC electrode prepared by two step cyclic voltammograms showed excellent electrocatalytic activity and stability for the oxidation of methanol. In addition, the crystal structure and the composition of the despoited platinum nanoparticles were investgated with the help of transmission electron microscope, the X-ray diffraction and electrochemistry method. The results indicated that the mean average size of the despoited platinum nanoparticles was 32.5 nm and the orientation of the nanoparticles was determined by (111) plane. |
