Hydrothermal synthesis of VO2(B) nanoribbons by a mixed-oxidation state precursor route

摘要

Highly crystalline metastable phase VO2(B) nanoribbons were fabricated on a large scale by hydrothermally treating a mixed-oxidation state vanadium (IV,V) precursor in PEG-600 aqueous solution. The nanOFibbons were uniform along the longitudinal direction with a length up to several micrometers, width in the range 50-100 nm, and thickness about 10 not, respectively. The growth process of nanoribbons and the factors influencing the morphology were also studied in detail. This novel precursor route provided a promising method with less reaction time and mild neutral aqueous environment, and the precursor could be potentially used in the fabrication of other nanostructured vanadium compounds.
