Micro-meso-materials from TS-1 seeds: structure-properties

摘要：

Using silicate solutions with TS-1 seed crystals mesoporous materials of type MCM-41 and MCM-48 were synthesized. The product materials possess hierarchical pore systems with the typical properties of microporous TS-1 and mesoporous MCM-41 and MCM-48 respectively. In order to show these materials features thermal analyses, multi nuclear NMR experiments, diffraction studies, XAS analyses and catalytic tests were performed. In this contribution we report on the evidence that mm-MCM-41(TS-1) and mm-MCM-48(TS-1) have distinct structures and specific properties attributed to the hierarchical structural organization of the silicate framework.
