Cation-Induced Coiling of Vanadium Pentoxide Nanobelts

Abstract

Abstract Single-crystalline V2O5·xH2O nanorings and microloops were chemically assembled via an ion-induced chemical spinning route in the designed hydrothermal system. The morphology and structure of products were investigated by means of scanning electron microscopy (SEM) and transmission electron microscopy (TEM). X-ray powder diffraction (XRD) measurement, energy-dispersive X-ray spectroscopy (EDS) microanalysis and thermal gravimetric analysis (TGA) revealed that the composition of nanorings and microloops is V2O5·1·1H2O. For these oxide nanorings and microloops, the cation-induced coiling growth mechanism of vanadium pentoxide nanobelts has been proposed on the basis of crystallographic structure of vanadium pentoxide. Our proposed chemical spinning process and the rational solution-phase synthesis route can also be extended to prepare novel 1D materials with layered or more complex structures.
