The adsorption of methanol on TiO2 (anatase) activated under vacuum at different temperatures has been studied by adsorption microcalorimetry and FT-IR spectroscopy. Both dissociative and undissociative chemisorption of methanol molecules have been found corresponding to the evolution of very high adsorption heats (qdiff > 150 kJ mol-1). At higher coverages, hydrogen bonded and dimeric adsorbed species are formed corresponding to differential adsorption heats of 50-120 kJ mol-1. © 1985.

Abstract
The adsorption of methanol on TiO2 (anatase) activated under vacuum at different temperatures has been studied by adsorption microcalorimetry and FT-IR spectroscopy. Both dissociative and undissociative chemisorption of methanol molecules have been found corresponding to the evolution of very high adsorption heats (qdiff > 150 kJ mol-1). At higher coverages, hydrogen bonded and dimeric adsorbed species are formed corresponding to differential adsorption heats of 50-120 kJ mol-1. © 1985.
