Synthesis of H₂V₃O₈ Single‐Crystal Nanobelts

Abstract

Abstract Orthorhombic H 2 V 3 O 8 single‐crystal nanobelts with a thickness of less than 30 nm and a length up to several hundreds of micrometers have been synthesized using bulky divanadium pentoxide powders as a precursor. The synthetic process is free of any templates and reducing agents. Divanadium pentoxide undergoes a redox reaction under hydrothermal conditions. The influences of pH, reaction time, and temperature on the morphologies of the resulting products have been investigated. The belt‐like H 2 V 3 O 8 with a high surface area may be beneficial to lithium insertion between the V 3 O 8 layers for application in batteries. (© Wiley‐VCH Verlag GmbH & Co.
