Abstract: The Pt/thioglycolic acid/GC composite electrode was prepared by self-assembling Pt nanoparticles on GC modified with thioglycolic acid. The composite electrode was characterized by SEM and cyclic voltograme method. The results show that the compact absorbing layer was formed because of thioglycolic characteristic absorb on the surface of GC electrode. The composite electrode, which had been self-assembled for 19 h, in the 2.5 mmol/L H2PtCl6 and 1.0 mmol/L PVP mixture solution, gave a good electrocatalytic oxidation of methanol in acidic system.

Key words: Self-assemble, Thioglycolic acid, Pt nanoparticles, GC electrode
