A series of CoO x /Al 2 O 3 catalysts was prepared, characterized, and applied for the selective catalytic reduction (SCR) of NO by C 3 H 8 . The results of XRD, UV–vis, IR, Far-IR and ESR characterizations of the catalysts suggest that the predominant oxidation state of cobalt species is +2 for the catalysts with low cobalt loading (≤2mol%) and for the catalysts...
The microkinetic reaction network of the oxidative dehydrogenation of ethane to ethene over Li/Dy/Mg/O and Li/Dy/Mg/O/Cl catalysts was investigated. With Li/Dy/Mg/O catalysts, the reaction kinetics is compatible with a heterogeneous-homogeneous radical based reaction mechanism. The formation of ethyl radicals on the surface is concluded to be the rate-determining step. In contrast, the reaction kinetics...
Four carbonaceous materials: carbon black, activated carbon, fullerene black and graphite, were employed in the NO-carbon reaction in order to study its structure sensitivity. The carbon structures were characterized by TEM and XRD analysis. The results obtained indicate that the internal structure of the samples employed greatly affects the reactivity of the samples towards NO. The reaction of NO...
The in-plane structure of stage-1 to stage-3 CuCl 2 graphite intercalation compounds (GIC) was investigated using X-ray and electron diffraction. A new 3D structural model of these CuCl 2 -GIC was defined based on a monoclinic, face-centred pseudo-orthorhombic unit cell and the X-ray and electron diffraction patterns were computed using this model. The modulations of the (00l) intensities...
Interaction of lanthanum(III) chloride with hydrogen forms of ferrierite, mordenite, zeolite L, and faujasite, under completely anhydrous conditions, is described. The course of the interaction has been studied by in situ i.r. and XRD techniques. No evidence of interaction between LaCl 3 and small-pore H-ferrierite was found. The other three structures investigated do interact with LaCl...
