摘要：
A series of ordered mesoporous Cr2O3-Al2O3 composite oxides synthesized via improved one-pot evaporation induced self-assembly strategy were investigated as the catalysts for catalytic dehydrogenation of isobutane. These mesoporous catalysts with good structural properties and thermal stability performed excellent catalytic properties. Besides, the effect of the ordered mesopore structure on improving catalytic properties was also studied. Compared with non-mesoporous catalyst, the current mesoporous catalyst could accommodate the gaseous reactant with more "accessible" active sites. Therefore, the present materials were considered as promising catalyst candidates for catalytic dehydrogenation of isobutane. (C) 2013 Elsevier B.V. All rights reserved.
