十多年来,钙钛矿型催化剂用于氧化反应的研究一直是一个活跃的领域.曾有人详细考察了CO在各种系列钙钛矿型催化剂上的氧化活化,催化剂的组份、晶形、焙烧温度和比表面对CO氧化活性的影响以及催化剂的SO_2中毒,吸附氧、晶格氧和氧空位在反应中的作用等.本文用脉冲反应、程序升温脱附、红外光谱研究了乙烷在Nd_0.7- For more than a decade, the study of perovskite catalysts for the oxidation reaction has been an active field.Once people have examined in detail the oxidation and activation of CO on various perovskite-type catalysts, the composition of the catalyst, the crystal form, Calcination temperature and surface area on the oxidation activity of CO and the effects of SO_2 poisoning, oxygen adsorption, lattice oxygen and oxygen vacancy on the reaction.In this paper, the effects of ethane on Nd_0.7-
