Hydrothermal synthesis of VO2 (B) nanorings with inorganic V2O5 sol†
Abstract
Metastable phase VO2 (B) nanorings were synthesized by hydrothermal treatment of inorganic V2O5 sol. It was found that oriented attachment growth and a subsequent rolling mechanism are essential for the formation of VO2 (B) nanorings under hydrothermal conditions.
