摘要：

Alumina-titania mixed oxides with nominal atomic ratios Al/Ti = 25 and 2 have been synthesized by cohydrolysis of Al(OsecBu)(3) and Ti(OBu)(4). The oxides were amorphous at 500 degrees C, showing only short range order. Ti was incorporated in alumina in a well dispersed way creating a true Al/Ti mixed oxide. The strength of surface acid sites and specific surface areas were increased at the higher Ti content. The TiO2 anatase phase was avoided and futile was formed directly at 900 degrees C.
