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 V2O5•nH2O xerogel is proved to give rise one-dimensional V3O7 and V6O13 phases. On the other hand, microwave-hydrothermal treatment of the same precursor leads to xerogel crystal structure distortion and to possible formation of superstructure.
