Synthesis and Characterization of Micro/Nanoscale VO₂(M) through Vanadylethylene Glycolate Decomposition

Thanks to a homemade dynamic vacuum system, fully crystallized VO₂ (M) is successfully synthesized in a merged step of vanadyl ethylene glycolate (VEG) decomposition and crystallization of VO₂ at high temperatures (>500 °C). During the whole process, vanadium valence (+4) is well maintained, and VEG microstructure plays an important role in the end-product size and shape. Finally, the suggested route appears well suitable for the mass production of VO₂ nanoparticles.
