Abstract 2-dimensional CdO nanorods were fabricated by electrospinning technique with poly(vinyl pyrrolidone) (PVP) as template and subsequently calcinated. SEM, TGA, DSC, FT-IR and XRD were used to characterize the morphology and structure of the as-prepared nanorods. The results show that the CdO nanorods is highly purified with a special morphology, namely, the nanorods stick together to form a porous film. The special morphology is related to the melting of PVP polymer during calcination. The prepared CdO nanorods were subsequently used to modify a glassy carbon electrode and then, with which the direct electrocatalytic oxidation of glucose was investigated. Results show that the CdO nanorods modified electrode has a better response to glucose and stronger resistance to the interference from AA, UA and ethanol rather than the electrode modified with CdO powder. The improved performance can be ascribed to the 2-dimensional CdO nanorods morphology, which enhanced the specific surface area, thereby enhancing the activity of electrode, facilitating the oxidation of glucose. So that, the fabricated CdO nanorods have the possibility of application as glucose sensor.
