查询词典 Oxygen

Under the experimental conditions, the evaluation of catalytic activity on direct decomposition of NO show that the presence of Cu is necessary for improving activity at 600~800℃ among La0.9Ce0.1Fe(subscript 0.8-x)Co0.2YO3(Y=Cu, Zn, Ni) series, and in which L.a0.9Ce0.1Fe0.7Co0.2Cu0.1O3 has the highest activity, the conversion of NO decomposition maintains 80% and nearly 100% at 750℃. H2-TPR result proves that the higher activity is related to the mobility of lattice oxygen which is beneficial to the reproduction of active site for NO decomposition.

在实验条件下，对NO的活性测试结果表明，L0.9Ce0.1Fe(下标 0.8-x)Co0.2YO3(Y=Cu， Zn， Ni)系列催化剂在600~800℃范围内，掺杂Cu的复合氧化物具有较高的催化分解活性，其转化率始终保持在80%以上，反应温度为750℃时，几乎100%转化。H2-TPR结果证明，其催化分解活性高的原因是Cu的掺入使晶格氧活动性增强。
