摘　　要：采用柠檬酸络合分解法合成了四方晶点、K_2NiF_4型结构的稀土复合氧化物LaSrMO_4(M=Mn,Fe,Co,Ni).实验结果表明,该类氧化物催化剂对恶臭和有毒的有机胺类化合物具有较好的催化降解作用,有机胺的氧化降解可达100%,而氮氧化物的产生率低于10%,其含量可大大低于排放标准.The tetragonal LaSrMO (M = Mn, Fe, Co, Ni) oxides with K2NiF4 structure have been prepared by citric-complex decomposition method. The experimental results indicated that foul and poisonous amine could be catalysis and decomposition effectively on the oxides above. The amine could be converted fully and the content of nitrogen oxide NO, was below 10 percent. Thus, the amount of NOX converted from the amine was greatly below the standard of exhaust emission.
