The results indicated that CNT/nano-TiO 2/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/cm 2, 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.安徽省自然科学基金 (No.0 0 0 4 531 7);; 安徽省高校科研基金(Nos.2 0 0 3kj1 4 1 ,2 0 0 4kj1 64zd)资助项
