Structural Studies of Adsorbates on Metal Oxides

ABSTRACT
Currently, there is a wave of interest, within the surface community,
in investigating metal oxide surfaces, both clean and adsorbate covered.
This is motivated by their importance both as regards basic science and
industrial applications (e.g. heterogeneous catalysis and gas sensors).
A vital part of this effort is the determination of the geometric structure
of these surfaces, many of which remain ill defined. In this seminar
I will present two such studies, both employing synchrotron radiation based
techniques. The first will be a scanned-energy mode PhD investigation
of the adsorption geometry of NO on a thin film of NiO(100). Secondly,
I will discuss C K-edge NEXAFS results obtained following the adsorption
of CO, CO2 and HCOOH, on clean and Cu exposed ZnO(0001)-O.
