| Abstract: | We describe the preparation of copper-based nanostructured electrode materials on carbon nanotubes supported by electrodeposition for direct glucose determination.The interest in exploring practical copper and carbon nanotubes composites electrode materials for sensor application was fascinated by the possibility of promoting electron transfer for kinetically unfavorable glucose oxidation reactions at lower overpotential and thus improving the sensitivity of glucose in electroanalysis.The morphologies of CNT/ITO and Cu/CNT/ITO were characterized by scanning electron microscopy(SEM).Enhanced current response(at a lower overpotential of 0.45 V),high stability,facile charge transport,as well as high catalytic activity towards glucose oxidation were observed at Cu/CNT/ITO.This study may provide a new insight into CNT/transitional metal-based composite nanomaterials via electrodeposition for fabricating novel and high performance sensors and devices. |
