Figure 5. (A) EA conversion, (B) CO₂ yield and (C) the Arrhenius plots of EA oxidation over the samples; Effects of 5.0 vol% vapor on EA oxidation over (D) LMO-S, (E) La₃Mn₂O₇, and (F) LMO-E conducted under the conditions: 200 °C, 70,000 h^-1 WHSV and 1,000 ppm EA; (G) the water contact angle tests of LMO-E, LMO-S and La₃Mn₂O₇; (H) long-term stability and (I) recyclability of the LMO-E for EA oxidation. EA: Ethyl acetate; LMO-S: LaMnO₃ prepared by the sol-gel method; LMO-E: LaMnO₃ prepared by the “top down” method; WHSV: weight hourly space velocities.
