Effect of Template Removal on Synthesis of Organic-Inorganic Hybrid Mesoporous MCM-48

摘要: Post-synthesis is used to synthesize organic hybrid inorganic mesoporous sieves. In this method, the activity and structure of base sieve are crucial obtain definable materials. The chemical physical properties can be largely changed either by final step its synthesizing processes, template removal which accomplished with oxidative thermal decomposition (burning) method or solvent extraction method. paper we compared two methods for post-synthesis MCM-48. When was extracted HCl/alcohol mixture, product showed larger pore size, volume better crystallinity case decomposition. reactivity surface silanol group free MCM-48 also checked an alkylsilylation reagent . Raman NMR spectra in test reaction indicated that more grafted sample after removed Direct synthesis vinyl-MCM-48 investigated characteristics were post-synthesis. From results, it suggested maintained grafting a good candidate porous material.
