Abstract
A series of supported vanadium oxide catalysts were prepared by the incipient wetness method as a function
of the support composition (Al2O3, SiO2, and USY), the metal oxide loading (0-1 wt %), and the impregnation
salt (vanadyl sulfate and ammonium vanadate). These catalysts have been studied by combined DRS-ESR
spectroscopies in order to
