摘要：
LaMnO3 and LaCoO3 perovskite nanoparticles have sprung up as the platinum group-metal (PGM)-free catalysts of NO oxidation to reduce NOX in the exhaust. In this paper, we present mesoporous LaMnO3 and LaCoO3 with rhombohedral structures prepared by a facile molten-salt synthesis method. LaMnO3 and LaCoO3 achieved NO oxidation performance with the highest NO conversions of 85% and 94% at 300 degrees C, which may be improved by K and Na introduced via flux.
