VOx species supported on Al2O3-SBA-15 prepared by the grafting of alumina onto SBA-15: structure and activity in the oxidative dehydrogenation of ethane
Original language description
This paper focuses attention on the grafting of alumina onto SBA-15 material and the subsequent impregnation of vanadium oxide species (VO (x) ). The role of alumina loading on the distribution of VOx species was studied in V-Al2O3-SBA-15 catalysts and its activity/selectivity in oxidative dehydrogenation of ethane. The activity of V-Al2O3-SBA-15 materials are correlated with the textural properties (N-2-adsorption/desorption isotherms), the distribution of VO (x) species (H-2-TPR and DR UV-vis) and the acidic properties (NH3-TPD). While V-SBA-15 mainly contains monomeric tetrahedrally coordinated VOx species, grafting of alumina on SBA-15 catalysts result in decreasing population of isolated monomeric VOx units in V-Al2O3-SBA-15 catalysts, increasing population of T (d) oligomeric VOx species and the formation of a low amount of octahedrally coordinated VOx species. V-Al2O3-SBA-15 catalysts are more selective to ethane (at the same conversion of ethane) compared to V-SBA-15 and V-alumina catalysts.
