英文摘要	The mesoporous chromia/alumina (Cr₂O₃/Al₂O₃) catalysts were successfully synthesized using a porous metal–organic framework MIL-101 (Cr₃F(H₂O)₂O(BDC)₃_nH₂O, BDC = 1,4-benzenedicarboxylate) as a molecular host and chromium precursor, inorganic aluminium salt as the aluminium precursor. The aluminium sources had the significant effects on the structure of the products. The formation of a-Cr₂O₃ phase was observed in the mesoporous catalyst (Cr₂O₃/Al₂O₃–C) prepared by AlCl₃_·6H₂O, whereas additional chromia alumina solid solution Cr_xAl₂_-_xO₃ phase was produced in the catalyst (Cr₂O₃/Al₂O₃–N) using Al(NO₃)₃·9H₂O as the aluminium precursor. The surface Cr species existed in the Cr⁶⁺ and Cr³⁺ state over the mesoporous catalysts. The Cr species had a strong interaction with the alumina support. Preliminary catalytic studies showed that the Cr₂O₃/Al₂O₃–N catalyst exhibited much higher isobutene selectivity and higher stability than the reference catalyst in the isobutane dehydrogenation. The maintainable dehydrogenation activity during the five dehydrogenation-regeneration cycles indicated high regenerative ability of the catalyst Cr₂O₃/Al₂O₃–N. Consequently, this study represents a feasible way toward the facile synthesis of the mesoporous chromia/alumina catalyst. Moreover, this work proposes a novel application of metal–organic framework.
