Abstract: Anew method named peptizinggelation method was used to synthesize TiSi dioxide composite, whose surface area is above 1000 m2/g. The character of this method is that Ti exists in the form of ion and ion cluster during the hydrolysis of Si(OC2H5)4. This is the progress on the cohydrolysis of Si(OC2H5)4and Ti(OC4H9)4.During the calcination of gelation, Ti-O-Si was formed with Ti element in the situation of SiO2crystal cell. This is confirmed by FTIRanalysis. TiSi dioxide composite with Ti molar fraction of 13.1% is mainly in the form of amorphous based on XRDanalysis, which reveals that TiSi dioxide composite is uniform in structure. Furthermore, extra Ti element presents on the surface layer of TiSi dioxide composite examined by Raman and EESanalysis. Owning to these two characters, TiSi dioxide composite prepared by peptizinggelation method becomes a good catalyst in the field of catalysis.

Key words: Ti-Si dioxide composite, Peptizing-gelation, Porous, High surface area
