Abstract
Cografted catalysts are synthesized by reacting surface -OH groups of a catalyst support with a solution containing two or more metal precursors. Under these circumstances factors such as temperature, concentration of metal precursors, time of cografting, and variations in metal precursor feeds can affect the surface metal densities. To understand influence of these parameters a compositional range of V-Zr cografted catalysts were synthesized using OV(O i Pr)3 and Zr(O n Bu)4 and studied. These catalysts were then characterized using ICP-OES, XRD, and XPS. XRD revealed that cografting was amorphous and XPS studies indicated that V5+ and Zr4+ were the only species present under ambient conditions.
