Acidity of Carboxylic Acid Ligands Influences the Formation of VO₂(A) and VO₂(B) Nanocrystals under Solvothermal Conditions.

ABSTRACT: Vanadium dioxide (VO₂) can adopt many different crystal structures at ambient temperature and pressure, each with different, and often desirable, electronic, optical, and chemical properties. Understanding how to control which crystal phase forms under various reaction conditions is therefore crucial to developing VO₂ for various applications. This paper describes the impact of ligand acidity on the formation of VO₂ nanocrystals from the solvothermal reaction of vanadyl acetylacetonate (VO(acac)₂) with stoichiometric amounts of water. Carboxylic acids examined herein favor the formation of the monoclinic VO₂(B) phase over the tetragonal VO₂(A) phase as the concentration of water in the reaction increases. However, the thresh
