摘要
A series of LaSrBO4 complex oxides were prepared by the citric acid complexion and characterized by XRD, XPS, H-2-TPR, NO-TPD and catalytic activity experiments. According to the investigations, LaSrMnO4 shows the best performance, the maximum conversion rate from NO to N-2 is up to 69%. The existence of oxygen is very important for the simultaneous removal of NOx and diesel soot particulates. The low temperature desorbed NO species would mainly influence the N-2 yield. The mobility of adsorbed oxygen species would mainly influence the selectivity of the reaction.
