Vanadium Oxide Nanotubes—A New Flexible Vanadate Nanophase

Abstract

Vanadium oxide nanotubes have recently been discovered as the main product of a sol-gel reaction that is followed by hydrothermal treatment in the presence of air, during which vanadium oxide sheets roll up, giving rise to the scroll morphology visible in the Figure. The scrolls are highly flexible, permitting numerous exchange reactions, and can be aligned using micromolding in capillaries.
