摘　　要：用不同链长的有机胺柱撑镧铌酸,采用X射线衍射、热重、差热等分析方法对合成的各种产物进行表征。结果表明,随着插入的有机胺链增大,产物的层间距增大,热稳定性提高,且有利于铂的交换和插入。正壬胺的柱撑后镧铌酸的层间距可以达到2.91nm。Amine-pillared lanthanum niobates with different chains length as pillars were characterized with XRD, TG and DSC. The results showed that the interlayer distances and the thermal stability of lanthanum niobate acids increased with the increase of the length of organic amine chains. Additionally, it benefited Pt intercalating lanthanum niobate. C9H19NH2-pillared lanthanum niobate acid possessed a higher interlayer distance of 2.91 nm.
