Electrocatalytic oxidation of glucose on carbon nanotube/nanocrystalline TiO2 film loaded Pt (CNT/nano-TiO2/Pt) complex electrode was investigated by cyclic voltammetry and chronopotentiometry. The results indicated that CNT/nano-TiO2/Pt complex electrode has high catalytic activity to the electrochemical oxidation of glucose in alkaline media, and the peak current density of oxidation of glucose is up to 13 mA/cm2, which is one time higher than that on a platinum electrode. The complex electrode performance is stable, and it is strong resistant to poisoning and difficult to oxidize oscillatory. It is a highly catalytic electrode for using in glucose fuel cell and glucose sensor.

Key words: carbon nanotube, nanocrystalline TiO2, glucose, Pt loaded complex electrode, electrocatalytic oxidation, fuel cell
