Acetic acid formation from methane and carbon dioxide via non-thermal plasma reactions towards an effective carbon fixation

Abstract

While direct CH₃COOH formation from CH₄ and CO₂ in a non-equilibrium condition is an ideal process, a dielectric-barrier discharge plasma reaction in the presence of CO₂ and isotopic CH₄ (¹³CH₄) revealed that the primly produced CH₃COOH can comprise both CH₄-derived carbons (i.e., no CO₂-derived carbon), indicating the importance of a particular CO₂ activation control in non-thermal plasma for an effective carbon fixation.
