It is well known that the surface acidity of a metal oxide is improved with the incorporation of another metal oxide to form a binary oxide. Thus, recently many kinds of mixed oxides were reported to show catalytic activity for particular reactions. Titania-silica mixed oxides are interesting materials. The combination of TiO{sub 2} and SiO{sub 2} generated very strong acid sites and showed high catalytic activity and selectivity for the amination of phenol with ammonia to produce aniline. In this paper the authors report the correlation between the band frequency of the silanol bending vibration in TiO{sub 2}-SiO{sub 2} catalysts and acid catalytic activity. For this purpose, the 2-propanol dehydration and cumene dealkylation were used as test reactions.
