Ordered mesoporous MgZnO was synthesized using mesoporous carbon CMK-3 as hard template and Mg(NO3)2·6H2Oaswell as Zn(NO3)2·6H2Oas precursors forMgOand ZnO, respectively. The morphology and mesoporous structure of the as-prepared MgZnO were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and N2 adsorption-desorption. The results demonstrate that MgZnO has a highly ordered mesoporous structure as well as crystalline pore walls. The average pore size is about 4.0 nm and the BET surface area is about 114.5 m2·g-1. Additionally, wide angle XRD results indicate that a solid solution of MgO and ZnO is formed. As a semiconductor material, mesoporous MgZnO has potential application in optical devices.
