    Abstract: MoO3 nanomaterials were synthesized by hydrothermal method as the precursor of β-Mo2C nanotubes. Then, the Mo-dopamine complex was synthesized by assisted ultrasonic stirring solvent. Finally, β-Mo2C nanotubes were prepared by programmed temperature processing. The nanotubes were characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM). Electrochemical methods such as cyclic voltammetry (CV), square wave pulse voltammetry (SWV), and linear sweep voltammetry (LSV) were used to study the catalytic oxidation of glucose. The experimental results showed that the β-Mo2C nanomaterial possess excellent performance. The impedance of the nanotubes was small, the rate of electrons conduction was fast, and the catalytic effect on the oxidation of glucose was excellent. The open current potential (OCP) of the constructed glucose/O2 fuel cell was 0.47 V, the maximum current density of the fuel cell was 3.0 mA·cm-2, and the power density was 0.70 mW·cm-2.
