摘要：
The MoO2 nanorods (NRs) were synthesized by simple hydrogen reduction using the MoO3 nanobelts (NBs) as the templates. The growth mechanism of one-dimensional (1D) MoO2 nanostructure can be explained by the cleavage process due to the defects in the MoO3 NBs. Different I/V characteristics of individual MoO2 NRs were obtained at different bias voltages, which can be explained by Ohmic and Schottky conduction mechanisms, and the resistivity increased at high bias voltage probably because of the oxidation of MoO2 NRs with large specific surface area.
