摘要: 在多相催化领域中,尖晶石复合氧化物作为催化剂,有很大的实用性.Margoli,等对Li,Cu,Ti等助剂对尖晶石结构及丙烷完全氧化活性的影响曾进行过研究.Shibata等认为钾的添加能增加催化活性中心的数目,提高反应的选择性.

关键词: 助剂钾, Ni-Co-O, Zn-Co-O, 复合氧化物

Abstract: In this paper the additive effect of potassium promoter on the Ni-Co-O and Zn-Co-O composite oxide catalysts was investigated by using XRD,TPR and XPS techniques, Theresults show that the specific area of these catalysts increases 4~5 times by the potassiumaddition and the catalytic activity of acetone and alcohol oxidation is enhanced.

Key words: potassium promoter, Ni-Co-O, Zn-Co-O, composite oxide
