摘要：

Simultaneous incorporation of Al and Ti in the MFI-type framework is demonstrated by XRD, i.r. Si-29, and Al-27 MAS n.m.r. techniques. The evidence for the presence of both Al and Ti in the silica matrix has been obtained by Si-29 MAS n.m.r. as well as by framework i.r. (960 cm-1), XRD (unit cell expansion), ion-exchange capacity (K+/AlO2- = 0.96), and catalytic properties for acid and oxidation functions in aluminotitanium silicate (Al-TS-1) molecular sieves.
