摘要
本文报道了采用水热法合成稀土杂原子沸石La-AlZSM-5。它的结晶度较高,且具有ZSM-5结构特征。利用XRD、IR、SEM、元素组成分析等物化手段进行表征。实验结果表明,稀土镧原子进入了沸石的骨架。合成的重现性较好。
Rare-earth hetero-atom La-A1ZSM-5 zeolites are prepared by the hydrothermal synthesis method. The zeolite has the structure of ZSM-5 and has high crystallinity. The zeolite is examined by means of XRD,IR, SEM and chemical analysis. Results show that the rare-earth atom La has entered into the crystal lattice. Reproducibility of synthesis is good.
