Abstract
Real-time observation of absorption and desoption processes of hydrogen in palladium-gold alloys was performed by means of ambient-pressure X-ray photoelectron spectroscopy. We succeeded AP-XPS measurements in the presence of nitrogen gas at a pressure of 100 mbar using a newly developed apertrure nozzle. With the improved apparatus, we conducted AP-XPS experiments of the Pd-Au alloys in hydrogen, and detected changes in the chemical states of Pd and Au in the alloys related to a metal-hydride phase transition.
