Modeling the Time-Dependent O3 Uptake on a Methane Flame Soot Coating Under Conditions of Competitive O3/NO2 and O3/N2O5 Adsorption
The uptake of O 3 (1 × 10 12 –5× 10 13 cm −3 ) on a methane soot coating preliminarily exposed to N 2 O 5 , is studied using a flow reactor with a movable insert. Based on the dependence of the ozone uptake coefficient on the exposure time and O 3 concentration, the uptake mechanism is established a...
