Özet

Single oxides of Ti and Zr incorporated SBA-15 were prepared and characterized by N-2 adsorption, NMR, and XPS techniques. Si-29 MAS NMR results suggest the formation of Si-O-X linkages (X: Ti or Zr) by an increase in the ratio of Q(3)/Q(4) in the presence of Ti or Zr. XPS analysis of Ti-SBA-15 catalysts indicate the presence of Ti-O-Si bonds in addition to Ti-O-Ti and Si-O-Si bonds, supporting the NMR evidence.
