摘要：

Infrared spectra are reported for acetophenone and its 4-methoxy derivative adsorbed on titania. Adsorption involved ligation via carbonyl oxygen atoms to Lewis acidic Ti4+ sites followed by slow enolisation and subsequent condensation to, for acetophenone, dypnone. Surface carboxylate species were formed at 353 K. Acetophenones are unsatisfactory indicators for testing the Bronsted acid character of oxide surfaces. (C) 1998 Elsevier Science B.V.
