Synthesis of Micro-/Nano Urchin-like VO2 Particle and Its Decolorization of Methylene Blue

In this article, micro-/nano urchin-like VO2 particles were successfully synthesized by hydrothermal method. Vanadium pentoxide (V2O5), oxalic acid (C2H2O4) and sodium dodecyl sulfate (SDS) surfactant were used as reagents for the synthesis of VO2. The article reports on the synthesis procedure of VO2 nanorods and micro-/nano urchin-like VO2 structure and evaluates the methylene blue (MB) adsorption properties. Morphology and particle size of VO2 were observed by FE-SEM. The VO2 formation phase was studied by XRD. Raman spectroscopy was also used for characterizing VO2. Micro-/nano urchin-like VO2 structure shows good MB adsorption properties that have potential applications in dye-contaminated water treatment.
