| Abstract: | Single oxides of Ti and Zr incorporated SBA-15 were prepared and characterized by N2 adsorption, NMR, and XPS techniques. 29Si 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. |
