Differences in physical and chemical properties of vanadium oxide nanomaterials synthesized by hydrothermal and microwave-hydrothermal methods

An influence of heating mode of a reaction system on phase composition and morphology of products during hydrothermal and microwave-hydrothermal synthesis of vanadium oxide nanomaterials is presented at the current work. The common hydrothermal treatment of V$_{2}$O$_{5}$ $\cdot$ nH$_{2}$O xerogel is proved to give rise one-dimensional V$_{3}$O$_{7}$ and V$_{6}$O$_{13}$ phases. On the other hand, microwave-hydrothermal treatment of the same precursor leads to xerogel crystal structure distortion and to possible formation of superstructure.
