An oxides-hydrothermal approach from bulky V{sub 2}O{sub 5} powder to V{sub 3}O{sub 7}.H{sub 2}O nanoribbons or V{sub 3}O{sub 7} nanoflowers in various ethanol/water mixed solvent

V{sub 3}O{sub 7}.H{sub 2}O nanoribbons and V{sub 3}O{sub 7} nanoflowers are firstly obtained via facile oxides-hydrothermal (O-HT) route. V{sub 2}O{sub 5} bulk-phase powder is directly used as precursor. The 1:1 ethanol/water and absolute ethanol are made as solvent for obtaining nanomaterials of vanadium oxides with different morphologies and structures. Characterizations of the samples are carried out using XRD, TG, FTIR, Raman-Spectra, SEM, TEM, HRTEM, SAED, and UV-vis. The large-scale fine ribbon-like V{sub 3}O{sub 7}.H{sub 2}O nanobelts with thickness ca. 20 nm and length ca. 20-40 {mu}m are obtained in 1:1 (v/v) ethanol/water mixed solvent. The V{sub 3}O{sub 7} nanoflowers are constructed by numerous whisker-like nanocrystal or petal-like are obtained in absolute ethanol solvent with the thickness about 20 nm and the size ca. 2-3 {mu}m. The formation mechanism of the sample is discussed.
