摘要:
以粒径约1 μm 的单分散三聚氰胺-甲醛微球制备得到胶体晶体模板,采用低过饱和沉淀法制备的镁铝摩尔比为2∶1的镁铝水滑石,将合成的水滑石悬浊液通过毛细效应的作用填充至胶体晶体模板间,待固化后经过煅烧去除胶体晶体模板,制备有序多孔镁铝水滑石。通过傅里叶红外光谱、X射线衍射分析、热重分析、差示扫描热分析、扫描电子显微镜对有序多孔镁铝水滑石的结构及形貌进行表征。结果表明,当加入体积分数为5%镁铝水滑石悬浊液时,去除模板后可得到孔径大小较为均一且排列有序的多孔镁铝水滑石。
Abstract:
The colloidal crystal templates were prepared by using monodisperesed melamine formaldhyde microspheres with particle sizes about 1 μm, and the Mg-Al hydrotalcite-like compounds with 2:1 mole ratio of Mg and Al were successfully synthesized by a supersaturated precipitation method. Then the magnesium aluminum hydrotalcite serous was filled into the colloidal crystal templates with the effection of capillary, and the colloidal crystal templates were removed by calcification after the solidification process. The morphology and structure of orderly porous magnesium aluminum hydrotalcite were characterized by Fourier transform infrared spectroscopy,X-ray diffraction analysis,thermogravimetric analysis,differential scanning calorimeter and scanning electron microscopy. The results showed that the orderly porous magnesium aluminum hydrotalcite with more uniform aperture size was obtained when the volume fraction of magnesium aluminum hydrotalcite serous was 5%.
