用电化学循环伏安法和计时电位法研究了葡萄糖在碳纳米管/纳米TiO2膜载Pt (CNT/nano-TiO2/Pt)复合电极上的电催化氧化.结果表明,在碱性介质中CNT/nano-TiO2/Pt复合电极对葡萄糖的电氧化具有高催化活性,葡萄糖氧化峰电流密度高达13 mA/cm2,比铂电极上的增大一倍;复合电极性能稳定,抗中毒能力强,不易发生氧化振荡,是葡萄糖燃料电池和葡萄糖传感器的高活性催化电极.

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.
