摘　　要：采用球磨法制备了La_2NiO_4和BaCO_3混合催化剂,通过XRD、O_2-TPD等分析方法表征了其物相组成,并考察了该系列催化剂催化分解NO的性能。结果表明:BaCO_3的引入可以有效地提高类钙钛矿型复合氧化物直接分解NO_x的催化性能,这与BaCO_3相具有NO_x储存能力有关。The mixed catalyst of La2NiO4 and BaCO3 were prepared by ball -milling method. The samples were analyzed by XRD and 02 -TPD. Meanwhile, their catalytic performance for NO direct decomposition was also investigated. The results demonstrated that the addition of BaCO3 could enhance the capability of perovskite - like oxides for NO direct decomposition,which resulted from the properties of BaCO3 species on NOx storage.
