Single-phase ZnAl2O4 spinel has been prepared by a novel simple route using layered double hydroxides (LDHs) as a precursor. ZnAl2O4 spinel is directly obtained by calcination of zinc aluminum layered double hydroxide whose Zn/Al molar radio is 0.5 without further chemical treatment. The key feature of this method is that it affords uniform distribution of all metal cations on an atomic level in the precursors. The structural characteristics of the as-synthesized precursors and the result calcined products were obtained by X-ray diffraction (XRD) and scanning electron microscope (SEM).
