NO adsorption and diffusion on hydroxylated rutile TiO2(110).
We report a computational study of NO adsorption and diffusion on the hydroxylated rutile TiO2(110) surface performed with density functional theory (DFT) calculations corrected by on-site Coulomb corrections and long-range dispersion interactions. NO prefers to adsorb with its N-end down at surface Ti5c sites. The excess electron that is located at a subsurface site for the hydroxylated surfac...
متن کاملNon-innocent adsorption of Co-pyrphyrin on rutile(110).
Solar-light driven water splitting is a promising way for the sustainable production of molecular hydrogen, the latter representing an efficient carrier for energy storage and conversion into common liquid fuels. In search of novel catalysts for high-performance water splitting devices, Co-pyrphyrin (CoPy) has been recently synthesized and successfully used as a homogeneous water reduction cata...
متن کاملIon adsorption at the rutile-water interface: linking molecular and macroscopic properties.
A comprehensive picture of the interface between aqueous solutions and the (110) surface of rutile (alpha-TiO2) is being developed by combining molecular-scale and macroscopic approaches, including experimental measurements, quantum calculations, molecular simulations, and Gouy-Chapman-Stern models. In situ X-ray reflectivity and X-ray standing-wave measurements are used to define the atomic ar...
متن کاملA combined experimental and computational study on the adsorption and reactions of NO on rutile TiO2.
In this work we combined computational density functional theory with experimental infrared spectroscopy to determine the adsorbate structure of NO and its reaction products N(2)O(2), N(2)O, and NO(2) on rutile TiO(2). These reactions are important for the photo-catalytic reduction of NO in exhaust gas, but yet little is known about the mechanisms or the intermediates involved. The combination ...
متن کاملSurface Structure of TiO2 Rutile (011) Exposed to Liquid Water
The rutile TiO2(011) surface exhibits a (2 × 1) reconstruction when prepared by standard techniques in ultrahigh vacuum (UHV). Here we report that a restructuring occurs upon exposing the surface to liquid water at room temperature. The experiment was performed in a dedicated UHV system, equipped for direct and clean transfer of samples between UHV and liquid environment. After exposure to liqu...
