| 摘 要： | 采用分解无定形柠檬酸和乙二胺四乙酸聚合体法,合成了具有类钙钛矿型结构的LaSrMO4(M=Mn,Fe,Co,N i,Cu)催化材料,以己烷完全氧化为探针反应,运用XRD、BET、TPR、TPD、FT-IR、XPS等手段进行表征.结果表明:对己烷完全氧化性能的顺序为LaSrCoO4>LaSrN iO4>LaSrCuO4>LaSrFeO4>LaSrMnO4,且氧空穴和可移动晶格氧越多、比表面积越大及颗粒度越小,均有利于提高己烷完全氧化活性.

| Abstract: | The perovskite-type LaSrMO_(4)(M = Mn,Fe,Co,Ni, Cu) mixed oxides were prepared by amorphous citric and ethylene diamine tetraacetic acid complexes decomposition and investigated using XRD,FT-IR,BET,TPR,TPD and XPS methods.The catalytic behavior was examined in the total oxidation of hexane.The order of catalytic activity for the total oxidation of hexane was LaSrCoO_4>LaSrNiO_4>LaSrCuO_4>LaSrFeO_4>LaSrMnO_4.This is explained in terms of its more oxygen vacancies and mobile lattice oxygen,smaller particle size and larger BET surface areas. |
