Abstract:

La0.85K0.15CoO3 perovskite-tpye catalyst was prepared by a sol-gel method and characterized by catalytic activity analysis to study the effect of NO and O2 on the combustion of soot. The catalytic activity of La0.85K0.15CoO3 Catalyst was promoted with NO. No matter lean or rich oxygen conditions, the La0.85K0.15CoO3catalyst could ignite soot at low temperature. The results of XRD and FT-IR showed that La0.85K0.15CoO3 catalyst has the desired perovskite-type structure, ABO3.
