Advantages

Ethanol decomposition during discharge mainly via electron impact dissociation and Penning dissociation, e.g., C₂H₅OH + e → CH₂OH + CH₃ + e and C₂H₅OH + Ar* → CH₂OH + CH₃ + Ar

Density of some carbon radicals (CH and C) continues to increase due to neutral species reactions after discharge ceases
