In situ XPS at a bending magnet beamline: Study of the electronic structure of binary Cu/Zn catalysts

摘要: Introduction In situ X-ray photoelectron spectroscopy is a powerful tool for the investigation of dynamic processes studied in field material science and catalysis. Several examples application this technique can be found previous annual reports. The study catalyst under working conditions often requires complex gas feed an elaborated analytic to follow conversion phase during reaction. It might frequently unavoidable use hazardous substances (e.g. poisonous or flammable) as reactants. obvious that permanent endstation at beamline dedicated spectroscopic investigations fulfill these requirements much more efficiently than non-permanent installation. A broad range should performed beamline. An optical setup based on plane grating monochromator (PGM) collimated light most suitable because operation optimized specific needs users without any hardware modifications setting slit positions, mirrors). schematic view proposed layout Fig. 1.
