摘要：

Thermally stable lamellar crystalline zirconia (TSLCZ) was prepared by a reflux-hydrothermal hybrid method. ZrOCl2, NaOH and lauric acid (LA) were used as Zr source, precipitant and supramolecular template, respectively. TSLCZ is well crystallized and exhibits ordered lamellar superstructure and good thermostability at 500 degrees C. TEM confirmed the 1.0 nm periodic lamellar superstructure detected and calculated by SAXRD (1.04 nm), which is composed of 0.5 nm-thick framework and pore layers alternatively. The synthesis mechanism of TSLCZ via a LA template was proposed and discussed in thermodynamics. (C) 2014 Elsevier B.V. All rights reserved.
