Orientation of acetic acid hydrogen bonded to acetate terminated TiO<inf>2</inf>(110)
2020, Surface ScienceCitation Excerpt :APPES studies involved measurement at elevated pressures of the vapor at reduced temperatures. The photon energy was calibrated by reference to the C K-edge π* resonance of acetate on TiO2(110) at 288.8 eV [3], while the photoemission binding energy scale was calibrated using the O 1s binding energy of TiO2(110) at 530.4 eV [16]. Ambient pressure NEXAFS monitored the C KLL Auger peak of acetate/acetic acid, centred at EKE = 249 eV, as a measure of the surface X-ray absorption coefficient.

2017, Surface ScienceCitation Excerpt :Different minority formate species bonded in different configurations have also been reported. These minority species include a formate molecule oriented perpendicular to the oxygen bridging rows with one O atom bonded to a Ti5c atom and the other O atom bonded to a Ovac, site (type B) [24,43]. Formate bonded to a Ti5c atom and a hydroxylated Ovac (type D) has also been reported [16,44].

2015, Surface Science ReportsAdsorption and stability of malonic acid on rutile TiO<inf>2</inf> (110), studied by near edge X-ray absorption fine structure and photoelectron spectroscopy
2014, Surface ScienceCitation Excerpt :Carboxylic acids are widely believed to attach to rutile TiO2 (110) surfaces dissociatively via deprotonation, where the hydrogen atom is lost from the carboxylic acid group (leaving COO−) [15,16]. The majority of molecules then bond to the surface through the two oxygen atoms of the carboxylic acid group in a bridging bidentate structure, to two adjacent five-fold-coordinated titanium atoms on the surface [17]. Malonic acid is a simple dicarboxylic acid as shown in Fig. 1.
