Abstract

Abstract: It is reported for the first time that the Pt-TiO₂/Ccatalyst prepared with chemical reduction and sol-gel method showed the excellent electrocatalytic activity and stability for the electrooxidation of methanol. When the atom ratio of Ti to Pt in the catalysts is 1/2, the catalysts showed the best electrocatalytic properties. After the catalyst is treated at 500 ℃, the performance is further improved. It is hopeful to use the catalyst in the pratical DMFC.

Key words: Methanol, Pt, TiO₂, Fuel cell, Electrocatalysts
