摘要 通过XRD、H2-TPR、NO-TPD等分析测试手段,研究了一定量的BaO对不同温度制备的La1.6Sr0.4NiO4催化NO直接分解活性的影响。研究发现低温焙烧得到的样品对NO直接催化分解活性高于高温焙烧得到的样品,且催化剂本身活性越大,BaO对其催化NO直接分解的活性促进作用越大。 A certain amount of BaO was researched for the effection of NO decomposition over La1.6Sr0.4NiO4 prepared at different temperatures ,through XRD ,H2‐TPR ,NO‐TPD .It was found that the higher NO direct decomposition over La1.6 Sr0.4 NiO4 at lower temperature . If La1.6 Sr0.4 NiO4 has the higher activity for NO decomposition , BaO would have more effection for the activity of NO catalytic decomposition .
