Abstract:-ZrCH2C(CH3)3]2 groups were grafted on surface of MCM-41 by a reaction with the surface hydroxyls in a high vacuum system for the first time. Hydrolysis or oxidation of the grafted groups resulted in richness of zirconium on the surface of MCM-41. The properties and composition of the materials were characterized by elemental analysis, FTIR, solid-state NMR, XRD and pyridine adsorption.The results showed that the catalytic and adsorptive performance of the grafted ZrMCM-41 was better than that of the hydrothermally synthesized ZrMCM-41.
Keywords:ZrMCM-41  tetraneopentylzirconium  chemical grafting  preparation
