ZnO nano-rectangular framework-like structure from zinc hydroxide acetate plates

Abstract

Rectangular thick plates of layered hydroxide zinc acetate (LHZA) are synthesized by crystal growth in ethanolic-aqueous zinc acetate solution. The secondary nucleation and crystal growth of LHZA with two phases results in rectangular thick plates, which have clear facets with terraces. The control of Zn concentration and water/ethanol ratio would create the stable LHZA system because of the suppression of the dehydration and condensation reactions from the zinc hydroxide to the zinc oxide. Moreover, the LHZA is converted into a framework-like ZnO by a pyrolysis reaction. The unique morphology of LHZA and ZnO is reported. © 2012 The Ceramic Society of Japan.
