Recent Developments in APXPS at the Shanghai Synchrotron Radiation Facility.

In this technical report, we will discuss several recent developments at BL02B of the Shanghai Synchrotron Radiation Facility (SSRF), with our focus on I in-situ i capabilities by X-ray photoelectron spectroscopy and X-ray absorption spectroscopy (XAS). Compared with TEY mode XAS, the AEY mode XAS obtained from the I m i RAS can further increase the surface sensitivity. After 50 years of effort, near-ambient or ambient pressure X-ray photoelectron spectroscopy (NAP-XPS or APXPS) has become a useful tool for studying gas and liquid molecules in environmental science [[1], [3]]. Together with the I in-situ i capability of the APXPS system, the AP I m i RAS can extend the HERED mode XAS for the I in-situ i investigation of electronic structure. [Extracted from the article]
