TL;DR: In this article, the room temperature adsorption of pyridine on η-Al2O3 dehydrated at several temperatures in the 25-700°C range has been studied by i.r. spectroscopy, u.v.-vis reflectance spectrograph and microgravimetry.
Abstract: The room temperature adsorption of pyridine on η-Al2O3 dehydrated at several temperatures in the 25–700°C range has been studied by i.r. spectroscopy, u.v.-vis reflectance spectroscopy and microgravimetry.Several species are formed that can be identified on the basis of the spectroscopic features of the 8a ring mode, whereas the 8b mode, which is common to all species, yields the total amount adsorbed. Quantitative interpretation of the spectral data is carried out using a computer program.The adsorbed species are interpreted as follows: a liquid-like physisorbed species, a species H bonded to surface OH groups through the nitrogen lone pair and three Lewis coordinated species. The latter are assigned to purely octahedral, tetrahedral–octahedral and purely tetrahedral cationic sites, respectively.The reactions occurring upon Py desorption above 400°C are discussed and a different interpretation is given to that in the literature.

TL;DR: In this paper, the authors investigated the action of oxygen and water-related surface defects in situ by impedance spectroscopy, photoconductivity, photoluminescence, and optical transmission as well as by characterizing solar cells which were prepared under respective conditions.

TL;DR: In this article, a review illustrates how the high performance levels achieved in X-ray photoelectron spectroscopy at the third generation synchrotron facilities, in particular the reduced data acquisition time down to a second range, have made possible studies of surface processes in real time.
