Direct observation of H2 binding to a metal oxide surface.

چکیده
Inelastic neutron scattering is used to probe the dynamical response of H2 films adsorbed on MgO(100) as a function of film thickness. Concomitant diffraction measurements and a reduced-dimensionality quantum dynamical model provide insight into the molecule-surface interaction potential. At monolayer thickness, the rotational motion is strongly influenced by the surface, so that the molecules behave like quasiplanar rotors. These findings have a direct impact on understanding how molecular hydrogen binds to the surface of materials used in catalytic and storage applications.

Thin SnOx films for surface plasmon resonance enhanced ellipsometric gas sensing (SPREE)
Background: Gas sensors are very important in several fields like gas monitoring, safety and environmental applications. In this approach, a new gas sensing concept is investigated which combines the powerful adsorption probability of metal oxide conductive sensors (MOS) with an optical ellipsometric readout. This concept shows promising results to solve the problems of cross sensitivity of the...
متن کاملEnhanced Bioadsorption of Cadmium and Nickel by E. coli Displaying A Metal Binding Motif Using CS3 Fimbriae
Display of peptides on the surface of bacteria offers many new and exciting applications in biotechnology. Fimbriae is a good candidate for epitope display on the surface of bacteria. The potential of CS3 fimbriae of enterotoxigenic E. coli as a display system has been investigated. A novel cell surface display system with metal binding property was developed by using CS3 fimbriae. Short metal ...
متن کاملHydrogen loading of oxide powder particles: a transmission IR study for the case of zinc oxide.
Many hydrogenation reactions are catalyzed by metal oxides. A particularly important case is the synthesis of methanol from syngas (H2, CO, CO2). Although presently mainly ZnO-supported Cu particles are used in the technical process, ZnO alone is also active as a catalyst for this process. According to the standard model the sources for the hydrogen species in the hydrogenation reactions are hy...
متن کاملElectrolysis of water on oxide surfaces
In this paper, density functional theory (DFT) calculations are performed to analyze the electrochemical water-splitting process producing molecular oxygen (O2) and hydrogen (H2). We investigate the trends in the electro-catalytic properties of (110) surfaces of three rutile-type oxides (RuO2, IrO2, and TiO2). The two first of these oxide anodes show lower O2-evolving over-potentials than metal...
