Abstract AITranslate

Using La(NO3)3 and Co(NO3)2 as raw materials,rare earth perovskite LaCoO3 powder was prepared by citric acid complexation and ammonium carbonate precipitation,respectively.Products were characterized by SEM,XRD,specific surface area analyzer and laser particle size analyzer.The results show that the rare earth perovskite LaCoO3 powder can be prepared by calcination above 600℃,and the surface structure is the flocculent structure of honeycomb foam.With the increase of calcination temperature,the surface will be sintered at different degrees.The sample prepared by citric acid complexation has high purity,stronger sintering resistance and smaller particle size,the efficiency of catalytic denitrification is over 90%.
