Acidic and catalytic properties of hierarchical zeolites and hybrid ordered mesoporous materials assembled from MFI protozeolitic units
Original language description
Two types of MFI zeolitic materials with improved accessibility, hierarchical zeolites and hybrid ordered mesoporous materials are here compared in terms of textural, acidic and catalytic properties. In both cases, protozeolitic units were employed as starting building blocks, the growth of which was perturbed by a silanization agent (hierarchical ZSM-5) or controlled by assembling around surfactant micelles (hybrid ordered mesoporous material, HZM). Likewise, two standard samples (nanocrystalline ZSM-5and Al-MCM-41) were used as reference. Nitrogen adsorption measurements confirmed the presence of a secondary porosity and a high share of non-microporous surface area in hierarchical ZSM-5, whereas no significant amount of micropores was detected in the hybrid HZM sample. However, 27Al MAS NMR measurements indicated that zeolitic fragments are present within the walls of the latter sample.
