Core-Level Binding Energy Reveals Hydrogen Bonding Configurations of Water Adsorbed on TiO2 (110) Surface
Kamal, C.; Stenberg, Nader; Walle, Lars Erik; Ragazzon, Davide; Borg, Anne; Uvdal, Per; Skorodumova, Natalia V.; Odelius, Michael; Sandell, Anders (Peer reviewed; Journal article, 2021)Using x-ray photoelectron spectroscopy of the oxygen 1s core level, the ratio between intact (D2O) and dissociated (OD) water in the hydrated stoichiometric TiO2ð110Þ surface is determined at varying coverage and temperature. ... -
Effects of K adsorption on the CO-induced restructuring of Co(11-20)
Strømsheim, Marie Døvre; Svenum, Ingeborg-Helene; Farstad, Mari Helene; Li, Zheshen; Gavrilovic, Ljubisa; Guo, Xiaoyang; Lervold, Stine; Borg, Anne; Venvik, Hilde Johnsen (Journal article; Peer reviewed, 2017)The location of potassium (K) on Cobalt (Co) and its effect on adsorption and adsorption-induced surface restructuring is important for understanding the deactivation of Co Fischer-Tropsch catalysts and the nature of the ... -
Investigations of PdAu membranes and model systems for production of pure hydrogen
Sørvik, Linn Cecilie (Master thesis, 2015)Hydrogen production from carbon-containing energy sources can capture the CO2 on site, and therefore reduce the contribution to global warming. The only emission when energy is produced through a fuel cell is H2O. Another ... -
Near Ambient Pressure XPS Investigation of CO Oxidation Over Pd3Au(100)
Strømsheim, Marie Døvre; Knudsen, Jan; Farstad, Mari Helene; Sørvik, Linn Cecilie; Guo, Xiaoyang; Venvik, Hilde Johnsen; Borg, Anne (Journal article; Peer reviewed, 2017)The CO oxidation behavior under excess oxygen and near stoichiometric conditions over the surface of Pd3Au(100) has been studied by combining near-ambient pressure X-ray photoelectron spectroscopy and quadrupole mass ... -
Palladium alloy model systems forunderstanding the surface properties of Pd-based membranes and catalysts
Fernandes, Vasco (Doctoral Theses at NTNU, 1503-8181; 2014:9, Doctoral thesis, 2014)Palladium has high solubility, permeability and selectivity for hydrogen, thus being a suitable membrane material for hydrogen separation. In addition, palladium is a versatile catalyst with applications in industrial ... -
Pd-based Membranes for Hydrogen Separation - Membrane Structure and Hydrogen Sorption and Permeation Behavior
Næss, Live Nova (Master thesis, 2013)Efficient separation of hydrogen from gas mixtures is a truly enabling technology for hydrogen as an energy carrier. Palladium(Pd)-based membranes are 100% selective to hydrogen, but need to be made thin, yet without defects ... -
Reversed Hysteresis during CO Oxidation over Pd75Ag25(100)
Fernandes, Vasco Rafael P; Van der Bossche, Maxime; Knudsen, Jan; Farstad, Mari Helene; Gustafson, Johan; Venvik, Hilde Johnsen; Grönbeck, Henrik; Borg, Anne (Journal article; Peer reviewed, 2016)CO oxidation over Pd(100) and Pd75Ag25(100) has been investigated by a combination of near-ambient-pressure X-ray photoelectron spectroscopy, quadrupole mass spectrometry, density functional theory calculations, and ... -
Structure of Clean and Oxidized PdCu(100) Surfaces at the Atomic Scale
Aase, John Fjermestad (Master thesis, 2012)In this thesis, clean and oxidized Pd(57)Cu(43)(100) single crystal surfaces were studied by LEED, STM and XPS in UHV conditions. The clean sample annealed to 300 degrees C has been found to either consist of ordered domains ... -
Thickness dependent effects of solubility and surface phenomena on the hydrogen transport properties of sputtered Pd77%Ag23% thin film membranes
Vicinanza, Nicla; Svenum, Ingeborg-Helene; Næss, Live Nova; Peters, Thijs; Bredesen, Rune; Borg, Anne; Venvik, Hilde Johnsen (Journal article; Peer reviewed, 2015)The hydrogen solubility and permeation in Pd77%Ag23% membranes have been determined as a function of temperature and membrane thickness. Unexpectedly, the solubility of hydrogen is found to systematically increase as the ...
