Новый способ получения нового типа нанотрубок оксида ванадия

Abstract

Представлены экспериментальные результаты, свидетельствующие о существовании принципиально новых механизмов образования как тонких (<150 нм), так и толстых (>250 нм) нанотрубок оксида ванадия. Проведена механохимическая обработка порошка оксида ванадия с варьированием навески оксида ванадия, объема спирта(или воды), продолжительностью активации. Исследование полученных образцов проведены с использованием трансмиссионной электронной микроскопии, рентгенофазового анализа.

The results of studying the morphology and microstructure of vanadium oxide (V) formed during a ball milling of V2O5 power in a planetary mill in the presence of ethanol are presented. Ball milling of V2O5 samples were studied by means of IR spectroscopy and XDR analysis. The morphology of nanotubes is investigated by means of high-resolution transmission electron microscopy. The length of nanotubes is comparable with that of crystals of an initial V2O5 power, and they have a scroll-like structure of layers. The formation of V-containing monolayers, scrolling of which leads to the formation V2O5 nanotubes, most likely proceeds due to a plastic deformation of the V2O5 crystal lattice facilitates the crystal cleavage. It is proposed for the first time to name the nanosized objects with properties depending on their size and morphology as “nanochemical”. They are essentially the main subject of nanochemistry as a branch of science.
