FT-IR characterization of the surface acidity of different titanium dioxide anatase preparations
TL;DR: In this article, the surface chemistry of anatase, in particular acidity, greatly depends on the preparation of the sample, both through the resulting morphology and the presence of surface impurities.

Infrared Spectroscopy Investigation of the Acid Sites in the Metal–Organic Framework Aluminum Trimesate MIL-100(Al)
Christophe Volkringer,Hervé Leclerc,Jean-Claude Lavalley,Thierry Loiseau,Gérard Férey,Marco Daturi,Alexandre Vimont +6 more
TL;DR: In this paper, the infrared spectra of MIL-100(Al) have been recorded after evacuation from room temperature up to 623 K. The results show the presence of impurities like carboxylic acid and nitrates resulting from the synthesis step, explaining the low amount of Al-OH groups detected.
