Abstract
We have performed a quantitative structure determination of the (root 5 x root 5) R27 degrees surface oxide, formed on Pd(100) under semi-realistic conditions for catalytic CO oxidation, using in situ high-energy surface X-ray diffraction. We describe the experiment and the extraction of quantitative data in detail. The structural results are in agreement with previous reports of a system consisting of a single layer of PdO(101) formed in pure O-2 on top of Pd(100) and studied under ultra-high vacuum conditions.
