Reaction mechanism of toluene decomposition in non-thermal plasma: How does it compare with benzene?

Authors:

Abstract
• The detailed mechanism of toluene destruction in an NTP system was revealed by SVUV-PIMS and quantum chemistry. • The decomposition processes of toluene and benzene in the NTP process were compared in detail. • The methyl group in the toluene changed the stability of the molecular structure. • The methyl group in the toluene participates in or initiates reaction pathways different from benzene only system. • O-benzoquinone was identified as an important intermediate contributing to the difference of reactions between toluene and benzene decomposition processes.
