摘要

A series of La_1-xBa_xCoO₃ (x = 0, 0.1, 0.2, 0.3) perovskites were synthesized by the modified sol-gel method, and their activities for NO oxidation were investigated as well. The relevant structural characterizations of the prepared catalysts were conducted by XRD, ICP, BET, FTIR, TEM, H₂-TPR and NO-TPD. The performance evaluation indicated that introduction of Ba at the A-site in LaCoO₃ greatly improved the activity for NO oxidation. The best performance with NO conversion of 93% at 265 °C was obtained on La_0.9Ba_0.1CoO₃. Additionally, the Ba-doped LaCoO₃ had better performance than that of the classical Pt/Al₂O₃ catalyst, implying that the non-noble catalysts could be considered as potential substituting candidates for noble metal-based catalysts.
