Titania modified SBA-15 as the support for molybdenum based catalysts

The series of titania modified SBA-15 supports were prepared in post synthesis applying titanium isopropoxide solutions and appropriate amounts of SBA-15. These Supports were used for preparation of molybdenum based catalysts. Ammonium heptamolybdate and molydenum carbonyl were applied as the source of Mo. Results confirm that this method of molydenum catalysts synthesis do not cause significant changes in symmetry of SBA-15. The decrease of surface area and channel dimensions are the main effects of SBA-15 modifications both with TiO2 and Mo species. Only Lewis acid sites were Found upon incorporation of titania on SBA-15. The use of different Sources of Mo leads towards different oxidized molybdenum Species which call be attractive in generation of their sulfided or nitrided forms.
