Center for Functional Nanomaterials Seminar
"Heterogeneous Chemistry at Liquid/Vapor Interfaces Investigated with Photoelectron Spectroscopy"
Presented by Hendrik Bluhm, Fritz Haber Institute of the Max Planck Society, Department of Inorganic Chemistry, Faradayweg, Berlin, Germany
Monday, October 21, 2019, 11:00 am — Bldg.735 (CFN) 1st floor conference room
Aqueous solution/vapor interfaces govern important phenomena in the environment and atmosphere, including the uptake and release of trace gases by aerosols and CO2 sequestration by the oceans. A detailed understanding of these processes requires the investigation of liquid/vapor interfaces with chemical sensitivity and interface specificity under ambient conditions, i.e., temperatures above 200 K and water vapour pressures in the millibar to tens of millibar pressure range. This talk will discuss opportunities and challenges for investigations of liquid/vapor interfaces using X-ray photoelectron spectroscopy and describe some recent experiments that have focused on the propensity of certain ions and the role of surfactants at the liquid/vapor interface.
