| 摘 要： | 本文采用恒定pH值共沉淀法制备六种层板金属离子不同的层状双氢氧化物(LDH).通过傅立叶变换红外光谱仪(FT-IR)、X-射线衍射仪(XRD)和扫描电子显微镜(SEM)对LDH进行了表征,并利用热重分析(TG)研究了LDH的热分解行为.研究表明,不同金属离子对LDH的层间距、晶粒尺寸等参数有一定影响,团聚程度也有较大的差异.

| Abstract: | Six kinds of layered double hydroxides(LDH's) with different metallic ions were prepared using co-precipitation method at constant pH value.Fourier transform infrared spectroscopy(FTIR),X-ray diffraction(XRD) and Scanning electron microscope(SEM) were used to characterize the chemical and physical structure of LDH's.The results showed that different metallic ions had a certain influence on the interlayer distance,crystallite size and other characteristic parameters of LDH's.There were distinctions among the... |
