摘要：

Partial substitution of La by Ag, instead of Sr, in LaMO(3) (M = Co, Mn, Ni) perovskite causes a large increase in the catalytic activity of the perovskite in the complete combustion of dilute methane for its emission control, at low temperature (< 700 degrees C) and high space velocity (51000 cm(3) g(-1) h(-1)); Ag-doped LaCoO3 shows the highest methane combustion activity.
