Micromorphology and Characterization of V₂O₃ Nanoparticles Produced by the Liquid Phase Reduction-Heat Treatment

Abstract

The liquid phase reduction-heat treatment has been used to prepare V2O3nanoparticles in this paper. It is a novel method that the precursor was developed by Oxalic acid dehydrate (H2C2O4·2H2O) reduction of V2O5powder in anhydrous ethanol. V2O3nanoparticles were successfully obtained by thermal treatment of the precursor. The phase, composition, structure, and morphology of the as-obtained samples were verified by XRD, XPS, SEM and TEM measurements. Meanwhile, the possible formation mechanism of V2O3in the heat-treatment is briefly discussed by analyzing the DSC.

“…The 1345 cm −1 and 1588 cm −1 peaks are assigned to disordered carbon (D-band) and graphite carbon (G-band), respectively. [29][30][31] The intensity ratio of the D-band to the G-band is about 1.11, indicating its low graphitization. 32 Fig.…”
