The reactivity of non-thermal plasmas is complex, involving numerous species with a very broad energy spectrum. To compare experimental results with the modeling of various reactions involved, we chose to study the decomposition of acetone diluted in N2<\/sub>\/O2<\/sub> mixtures in the presence of a homogeneous discharge, specifically a photodischarged homogeneous discharge.<\/p>\n

The plasma reactor is coupled with a compact FTICR mass spectrometer (BTrap) using chemical ionization, which performs real-time analyses of the various volatile organic compounds present. BTrap allows for the identification and quantification of acetone and its degradation by-products via plasma in real time, specifically every 10 seconds.<\/p>\n

In this study, we demonstrated that the presence of oxygen significantly hampers acetone degradation and induces major changes in the reactions driven by the plasma, reflected in alterations to the distribution of by-products. While the primary products observed in gas mixtures without oxygen are nitrile compounds, they are replaced by oxygenated products, particularly formaldehyde, as well as nitrate and nitrite compounds including HNO2<\/sub>.<\/p>\n<\/div>\n<\/div><\/div>
