The synthesis of SBA-15 pane [5–13]. According to the literature, the use of titania as a was described previously in the literature [22]. Titania support material for dispersed vanadia as well as mixing dis- was deposited onto the silica support via incipient wetness persed titania to SiO -supported vanadia leads to a significant impregnation using a precursor solution of titanium(IV) iso- improvement of the catalytic activity in oxidation reactions propoxide (Ti(iOPr) , Sigma Aldrich, 99.999%) and 2-pro- [5, 6, 8, 12–15]. Due to its redox properties titania has been panol (anhydrous, Sigma Aldrich) with a concentration − 1 considered an active support material.
