Water vapour effects on secondary organic aerosol formation in isoprene ozonolysis
文献信息
Ryoji Yajima, Satoshi Inomata, Jun Hirokawa
Secondary organic aerosol (SOA) formation from isoprene ozonolysis was investigated using a Teflon bag reactor under dry and humid conditions. Both the number and volume concentrations of SOA were found to be decreased by the addition of water vapour. Gas- and particle-phase product analyses with a negative ion chemical ionization mass spectrometer show that oligomers composed of stabilized Criegee intermediates as the chain units contribute to the SOA formation and that water vapour inhibits stabilized Criegee intermediates from forming the oligomers, resulting in the suppression of SOA formation. Additionally, it is suggested that a portion of stabilized Criegee intermediates other than CH2OO have low reactivity toward H2O, and thus can be involved in the oligomer and SOA formation even under humid conditions. Volatility estimation predicts that the oligomers containing even one or two stabilized Criegee intermediates can be partitioned into the aerosol phase.

Physical Chemistry Chemical Physics

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
