The Methodology for Determining the Size of Vanadium Oxide Nanoparticles Using Electrothermal Atomic Absorption Spectrometry

Abstract

The synthesis of vanadium dioxide nanoparticles was achieved through the hydrolysis of vanadyl acetylacetonate, which was obtained from vanadyl sulfate. The thermochemical transformations that occurred during the heating of a colloidal solution of vanadium (IV) oxide in a graphite furnace were investigated using X-ray diffraction analysis and transmission electron microscopy. To determine the size of the nanoparticles, a series of vanadium (IV) oxide nanoparticle solutions were analyzed using the method of electrothermal atomic absorption spectroscopy.
