Comment on “Synthesis, characterization and growth mechanism of flower-like vanadium carbide hierarchical nanocrystals”

Abstract

This Letter is in response to a recent paper by Ma et al. (CrystEngComm, 2010, 12, 750–754) which arguably studied vanadium carbide nanostructures whereas all available evidence indicates the study of vanadium oxide. We feel that it is important to communicate to the community several inconsistencies so that the interesting material reported can be seen in the right light, especially with several groups nowadays having reported similar structures from vanadium oxide synthesis.
