The scanning electron microscopy,X-ray diffractometry and electrochemical tech-niques were used to study the surface structure and catalytic activity of highly dispersed plat-inum supported on glassy carbon electrode。 The results demonstrated that after high temper-ature treatment the dispersed platinum showed a tendency of monoorientation on the surfaceof glassy carbon, and yieldied large size microcrystals with regular morphology。 The high temperature treated Pt/GC was stable and possessed a relatively high catalytic activity to-wards methanol oxidation.
