Structural and morphological transformations of Zn–Al layered double hydrox…

Abstract. The Zn–Al layered double hydroxides (LDH) with Zn/Al molar ratio of 2 were prepared by coprecipitation, followed by hydrothermal treatment at various hydrothermal conditions. The phase transformation was observed, accompanied by drastical morphological changes. As the results indicated, in aqueous system the decomposition product was phase segregated into wurtzite ZnO and spinel…
