dc.description.abstract
Many studies have been conducted on the environmental impacts of combustion
generated aerosols. Due to their complex composition and morphology, their
chemical reactivity is not well understood and new developments of analysis
methods are needed. We report the first demonstration of in-flight X-ray based
characterizations of freshly emitted soot particles, which is of paramount
importance for understanding the role of one of the main anthropogenic
particulate contributors to global climate change. Soot particles, produced by
a burner for several air-to-fuel ratios, were injected through an aerodynamic
lens, focusing them to a region where they interacted with synchrotron
radiation. X-ray photoelectron spectroscopy and carbon K-edge near-edge X-ray
absorption spectroscopy were performed and compared to those obtained for
supported samples. A good agreement is found between these samples, although
slight oxidation is observed for supported samples. Our experiments
demonstrate that NEXAFS characterization of supported samples provides
relevant information on soot composition, with limited effects of
contamination or ageing under ambient storage conditions. The highly surface
sensitive XPS experiments of airborne soot indicate that the oxidation is
different at the surface as compared to the bulk probed by NEXAFS. We also
report changes in soot’s work function obtained at different combustion
conditions.
