Research Progress of Preparation and Mechanism of Nano-vanadium Oxide

Nanomaterial is a kind of materials with excellent mechanical properties. Now it has aroused a lot of attention from scholars at home and abroad. Vanadium oxide is characterized by the special layered structure and the thermochromic properties near the room temperature. The nano-vanadium oxide is widely used in the fields of electrochemical, catalysis, sensor, intelligent coating, optical information storage, optical switching elements, optical thermochromic, infrared detection, and electrical switching elements. More and more researchers have pay attention to the nano-vanadium oxide. The research on nano-vanadium oxide in recent years is studied in this article. The preparation method and the mechanism of the different dimension nano-vanadium oxide were summarized. The type of nanomaterials includes zero-dimensional nanomaterials(hollow nanospheres, nanoparticles), one-dimensional nanomaterials(nanotubes, nanorods, nanowires, nanobelts, et al), and two-dimensional nanomaterials(nanofilms). The main methods to prepare nano-vanadium oxide are the hydrothermal-solvothermal method, sol-gel method and reactive sputtering method. Hydrothermal-solvothermal method is often used to prepare the low dimensional nanomaterials. Sol-gel method and reactive sputtering method are often used to prepare the two-dimensional nanomaterials. Finally, the further works in research are prospected.
