Research Abstract

In situ electrochemical X-ray photoelectron spectroscopy (XPS) measurement was carried out utilizing an ultra-thin photoelectron window and hard X-ray from a synchrotron source. A cell filled with water was sealed by the ultra-thin photoelectron window and placed in a vacuum XPS apparatus. X-ray is irradiated to the vacuum side of the window, penetrates to the solution side and electrons emitted at the water/window interface are analyzed by an electron analyzer placed in vacuum.
