Fengxia Bao

Dr. Fengxia Bao is a PostDoc Fellow at the Paul Scherrer Institute (PSI), affiliated with the Laboratory of Atmospheric Chemistry. Her research focuses on the intersection of atmospheric chemistry and chemical kinetics, particularly in the context of the ReCLEAN-Nitrate project, which investigates photoinduced nitrate reduction in aerosols. Prior work includes studying biosphere-atmosphere exchange of nitrogen species, global biogeochemical nitrogen cycle modeling, heterogeneous NO2 reactions, and photochemical aging of particles.

• Current Project: ReCLEAN-Nitrate (Photoinduced Nitrate Reduction in Aerosols)
• Previous Projects: Biosphere-atmosphere nitrogen exchange, Global nitrogen cycle modeling, NO2 heterogeneous reactions, Particle photochemical aging

Her research spans atmospheric chemistry, chemical kinetics, and environmental science, with significant contributions to understanding HONO production mechanisms, ozone pollution dynamics, and multiphase reactions involving nitrate-containing particles. Key findings include the role of brown carbon in enhancing HONO/NOx production, novel NO2-to-HONO conversion pathways on soot, and quantifying reactive uptake coefficients in dynamic chamber systems.

Recent publications highlight her work on ozone pollution regulation through VOC reactivity analysis, HONO emissions from fertilized soils, and photochemical aging processes affecting particle composition and oxidizing capacity. She utilizes advanced instrumentation like dynamic chamber systems and field measurements at locations such as the North China Plain and Mt. Tai to validate chemical mechanisms and assess environmental impacts.
