以介孔碳为硬模板经过二次填充制备了介孔镁锌氧复合物.采用X射线衍射(XRD),透射电镜(TEM),扫描电镜(SEM),N2吸附脱附等手段对材料的结构及形貌进行了表征.结果表明,所制备的材料在具有高有序介孔结构的同时还具有结晶的孔壁.孔径尺寸均为4.0nm,比表面积均为114.5m2.g-1.广角XRD结果初步表明,材料中氧化镁和氧化锌复合形成了固溶体.该材料作为一种半导体材料有望在光学器件领域获得新的应用价值.
The mesoporous Mg-Zn composite was prepared by filling the mesoporous carbon into a hard template and characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), scanning electron microscopy (SEM) and N2 adsorption and desorption Structure and morphology were characterized.The results show that the prepared material has a highly ordered mesoporous structure and also has a crystalline pore wall size of 4.0nm, a specific surface area of 114.5m2.g-1. The result of wide-angle XRD shows that the composite of magnesium oxide and zinc oxide forms a solid solution, which is promising as a semiconductor material in the field of optics.
