首次合成了稀土元素掺杂的具有MFI结构的La-Si ZSM-5分子筛,并采用各种技术对所合成的分子筛进行了表征.XRD衍射表明所合成的微孔材料具有典型的MFI结构,N2吸脱附、FT-IR及SEM测试结果均表明镧原子进入了分子筛骨架.
The rare-earth doped La-Si ZSM-5 molecular sieve with MFI structure was synthesized for the first time, and the molecular sieve was characterized by various techniques.XRD diffraction showed that the synthesized microporous material has a typical MFI structure, N2 Absorption and desorption, FT-IR and SEM test results show that the lanthanum atoms into the molecular sieve framework.
