Abstract

A new chimie douce (soft chemistry) approach toward ultra-long single crystalline vanadium pentoxide (V2O5) nanobelts is presented. The synthesis involved thermal oxidation of a thin film of vanadium(IV)-oxy acetylacetonate (VO(acac)2). Self-assembly of intermediate oxygen deficient islands formed nanobelts with length up to millimetre scales. The belt width : thickness aspect ratio could be changed from ∼5 to 70 by simply increasing the heating time from 15 min to 2 h. Such samples are useful for probing the fundamental properties of the individual nanobelts, while the methodology solves a technical bottleneck for isolating 1D nanostructures that can be incorporated into devices.
