Abstract:
In this paper, one-dimensional nanowires and snowflake-like nanostructures had been successfully prepared in mixed solvent of glycol and water with using a simple mixed solvent thermal method. The nanowires have a diameter of about 60 nm and lengths of several micrometers. And the aspect ratio of length to diameter is more than 30. When the ratio of glycol to water changed from 10:1 to 1:5, the structures of the final products changed from snowflake-like nanostructures to nanowires. In this experiment, the ratios of glycol to water (10:1, 5:1, 2:1, 1:1, 1:2 and 1:5, respectively) were used. When the ratios were 1:1, 1:2 and 1:5, respectively, the results showed that the products were more close to nanowires structure. And the products were composed of V2O5 and FeVO4. When the ratios were 10:1, 5:1 and 2:1, respectively, it tended to form snowflake-like nanostructures. And the products were composed of V2O5 and Fe2V4O13. The microstructures and morphologies were investigated via transmission electron microscopy (TEM). And the compositions of the products were confirmed by X-ray diffraction (XRD).
