Synthesis of Crystalline Microporous Materials with New Composition under Extreme/Non-equilibrium Conditions

在过去的一个财政年度(2020财年)，我主要致力于将铂/锡金属团簇快速包覆到ZSM-5分子筛中用于丙烷脱氢，原位包覆可以在几分钟内快速完成，形成超细的铂团簇，并在结晶的同时被限制在高硅ZSM-5沸石中。锡的作用被认为是调节铂的分散。一锅法合成的铂/锡-ZSM-5沸石催化剂对丙烷脱氢制丙烯表现出很高的活性和选择性。此外，即使经过多次反应和再生，也可以保持催化剂的高活性。在Angewandte Chemie国际版上发表了一篇关于这个主题的论文。

In the past fiscal year (FY2020), I mainly worked on the fast encapsulation of Pt/Sn metal clusters into ZSM-5 zeolite for propane dehydrogenation.The in situ encapsulation can proceed very fast and complete in just a few minutes, where ultrasmall Pt clusters are formed and simultaneously confined into the high-silica ZSM-5 zeolite along with its crystallization. The role of Sn is supposed to modulate the dispersion of Pt. The one-pot synthesized Pt/Sn-ZSM-5 zeolite catalyst exhibits very high activity and selectivity for the dehydrogenation of propane to propene. Moreover, the high activity of the catalyst can be maintained even after multiple cycles of reaction and regeneration. A paper on this topic has been published on Angewandte Chemie International Edition.
