Abstract:The perovskite catalysts La0.gCe0.1NiO3 for the oxidation of carbon particles,nitric oxide,carbon monoxide and hydrocarbon in diesel vehicle exhaust gases were prepared by solution combustion synthesis,and characterized by means of XRD.And in terms of the catalyst activity evaluation,conversion efficiency of PM and the durability of catalyst for sulfur,the activity of four-way diesel exhaust catalyst was evaluated,and results showed that the catalysts exhibited obvious perovskite structure,the maximum conversions of NO were 25.03%,the light-off temperatures of the soot combustion were 235 ℃,and the temperatures for the complete combustion of C3H6 were 418 ℃,with good durability to the sulfur.
