Abstract

Abstract : Sodium acetate preferentially suppresses the growth along the c -axis during the hydrolysis formation of α-GaOOH particles. Abstract : Nearly monodisperse, single-crystalline gallium oxide hydroxide particles have been synthesized via a hydrolysis process in the presence of sodium acetate, under acidic conditions, at 70 °C. The presence of sodium acetate resulted in the formation of α-GaOOH particles shaped in the form of wedges, bound by four {110} and eight {212} faces (orthorhombic, Pbnm space group). Varying the sodium acetate concentration enabled us to control the shape of the wedge-like particles, by suppressing growth along the c -axis.
