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 plasma-catalytic decomposition process was proposed.
