摘要
采用高温固相法合成了层状钠钴氧化合物Na0.7CoO2,并用盐酸对其进行酸化,酸化后再与正丙胺进行酸碱反应,使正丙胺插入层间。最后,运用XRD,IR和TG-DTA等分析手段对插入正丙胺的Na0.7CoO2的结构进行研究。结果表明:正丙胺成功地插入了Na0.7CoO2的层间,使层间距从0.5401nm扩大到0.6976nm。
A layered compound Nao.7CoO2 was synthesized by solid state reaction at high temperature. Then Nao.7CoO2 was treated with 1 M hydrochloric acid for 24 h and the resultant, a protonated form of Nao.7CoO2 was further intercalated with n-propylamine by means of acid-base reactions. The final resultant compound Nao.TCoO2 was characterized by XRD, IR and TGDTA. The inspection results showed that n-propylamine was successfully intercalated into the protonated form of Nao.7CoO2 and its interlayer distance was enlarged from 0. 5401 nm to 0. 6976 nm.
