Abstract

An instrumentation is presented allowing to study the X-ray absorption edge spectra of light elements (z=3–15) in the surface-sensitive Auger yield detection at elevated pressures (mbar range). Heterogeneous catalysts can be studied for their surface electronic structure under working conditions in a flow-through reactor mode. An example of methanol oxidation to formaldehyde over copper metal is studied in detail. A new form of weakly bound atomic oxygen was found which only exists under reaction conditions. Its existence is linked to defect sites on the Cu. Several mechanistic predictions from earlier low-pressure studies could be verified with this in situ experiment.
