A facile hydrothermal method for the fabrication of one-dimensional MoO3 nanobelts

Abstract One-dimensional MoO3 nanobelts have been synthesized for the first time from molybdic acid in a solvent of oxalic acid with the addition of nitric acid via a facile hydrothermal method. The morphology and structure of the as-prepared nanocomposite have been thoroughly characterized by the combination of different techniques. According to XRD analysis, the obtained MoO3 nanobelts are single-crystalline with an orthorhombic structure. XPS analysis proves that the Mo is in its highest oxidation state of +6. In addition, the obtained nanobelts that have a width ranging from 100 nm to 300 nm, together with a length in micrometers are observed through TEM and FESEM. Furthermore, the possible growth mechanism is also investigated.
