Plasma-catalytic decomposition of low concentration ethyl acetate with LaMO3 (M = Co, Mn and Fe) perovskite catalyst was investigated in a coaxial dielectric barrier discharge (DBD) reactor. The combination of perovskite catalyst and plasma enhanced ethyl acetate decomposition, and the activity sequence was LaCoO3> LaMnO3> LaFeO3. Characterizations results indicated that the activation of surface oxygen species and amount of oxygen vacancies contributed to ethyl acetate decomposition remarkably. FT-IR analysis demonstrated that the employment of LaCoO3 catalyst also reduced the amount of unwanted by-products. Based on these results, reaction mechanism of ethyl acetate plasmacatalytic decomposition process was proposed.
