摘要: 利用醋酸铅分别与8-羟基喹啉、柠檬酸、草酸在低加热条件下进行固-固相配位反应,首先合成了不同的前驱配合物,进而经不同的热分解历程得到了纳米量级β-PbO粉体(黄色).利用元素分析、热重/差热分析对固相配位反应的可行性作了讨论.借助X射线衍射、透射电镜测试对合成的纳米粉体的物理性质作了表征.

关键词: 固相反应, β-PbO, 纳米粉体

Abstract: Nanosized β-PbO samples were prepared by solid state coordinations of Lead acetate with 8-hydroxyquinoline, citric acid and oxalic acid respectively. The resulted complex precursors were thermally decomposed to obtain nanosized β-PbO powders. Their physical properties were characterized and discussed by elemental analysis, TG-DTA, XRD and TEM tests.

Key words: solid state reaction, β-PbO, nanosized powders
