Use and production of nanotubes containing a mixed valence venadium

Abstract

Separable nanotubes are made from a transition metal oxide, preferably from a vanadium oxide of variable valence. They show a greater oxidation resistance than the carbon-based nanotubes known so far and offer many new and economic applications. The inventive nanotubes clearly show oxidation-reduction activities and are particularly suited as an active material for catalytic reactions.
