| 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,合成了镧掺杂的MCM-41介孔分子筛。通过X射线衍射(XRD)、傅里叶变换红外(FTIR)光谱、透射电镜(TEM)、紫外-可见(UV-Vis)光谱等测试手段对其孔结构和镧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和紫外-可见光谱表明镧被成功的引入到介孔骨架中。

| Abstract: | MCM-41 mesoporous molecular sieve incorporated by lanthanum （noted as La-MCM-41） was synthesized under hydrothermal condition using TEOS as Si sources,lanthanum nitrate as La supply and cetyltrimethyammonium bromide （CTAB） as mesoporous template.The pore structure and the existence of rare earth atom were characterized by XRD,FTIR,TEM and UV-Vis.XRD results show that the samples with a typical orderly arrangement of P6 structure.La can enter the framework of mesoporous material.FTIR and UV-Vis spectra show that La has been incorporated in the mesoporous skeleton. |
