摘要：Highly thermal stability is an essential property for propane dehydrogenation (PDH) catalysts that need to be regenerated frequently in oxidative atmosphere. A kind of hierarchical MgAl2O4 with flower-like morphology is prepared by alcohothermal method and used to support Pt and Pt-Sn. The materials are characterized by ICP-AES, SEM, TEM, XRD, Py-IR, and N-2 physi-sorption. Hierarchical MgAl2O4 supported Pt shows great thermal stability under oxidizing atmosphere at 800 degrees C. Supported Pt-Sn catalyst for PDH shows high stability of performance during 10 cycles of dehydrogenation-regeneration runs. The high stability could, originate from the existence of relatively abundant MgAl2O4(111) facets on MgAl2O4. (C) 2016 Elsevier B.V. All rights reserved.
