摘要
以十六烷基三甲基溴化铵(CTAB)为表面活性剂,正硅酸乙酯(TEOS)为硅源,采用水热晶化法,合成了钕掺杂的MCM-41介孔分子筛.通过X射线衍射(XRD)、傅里叶变换红外(FT-IR)光谱、透射电镜(TEM)等测试手段对其孔结构和钕原子的存在状态进行了表征.XRD和TEM结果表明,合成样品具有典型的二维六方有序介孔结构,样品的傅里叶变换红外光谱表明钕被成功的引入到介孔骨架中.
Mesoporous molecular sieve MCM-41 doped neodymium is prepared by hydrothermal method using CTAB and TEOS as surfactants and silicon source, respectively. In addition, the porous structure and the presence of Nd are characterized by XRD, FT-IR, TEM and so on. The results show that the product exhibits hexagonal mesoporous struc- ture and Nd has been introduced into the mesoporous frameworks.
