Sn-containing hexagonal mesoporous silica (Sn-HMS) has been synthesized and evaluated for catalytic dehydrogenation of propane. XRD, HRTEM and XPS characterizations jointly evidence that, the Sn species are probably embedded into the lattice of HMS bulk at a relatively low Sn loading amount. Compared with Sn/SiO2 samples prepared by conventional impregnation method, Sn-HMS catalyst exhibits inspiringly...
The catalytic activity of a novel catalyst Mo/MgAl 2 O 4 was studied in isobutane dehydrogenation, and the effect of calcination temperature has been comprehensively investigated. For catalysts with MoO 3 loading below monolayer coverage (5Mo/MgAl 2 O 4 ), isobutane conversion increases with calcination temperature, while the selectivity to isobutene decreases...
