The Assembling And Doping Of The Mesoporous Materials

There are two parts in this paper: the synthesis of MCM-41 assembling bodies and the synthesis of Si-MCM-48 and M ( Zr Cu Cr Zn Ni)-MCM-48.1. MCM-41 acetylsalicylic acid, MCM-41 phen, a series of MCM-41 acetylsalicylic acid Eu³⁺ (Tb³⁺) and MCM-41 phen Eu³⁺(Tb³⁺ ) were prepared and were characterized by XRD, IR and fluorescence spectrum. The results showed that the assembling bodies had the mesoporous structures. The fluorescence analysis showed that the assembling bodies had strong intensity of fluorescence. The intensity had the relationship with the content of RE oxide.2. Highly ordered Si-MCM-48 and M (Zr Cu Cr Zn, Ni)-MCM-48 were synthesized using the CTAB, TEOS, NaOH etc. The samples were characterized by XRD, UV, HRTEM, TG-DTA and pore distribution techniques. The XRD results showed that the MCM-48 was synthesized. The UV results showed that the transitional metal ions could hardly enter the framework of MCM-48. We should change the conditions to go on more research.
