【摘要】 采用低饱和共沉淀法制备Zn-Al LDHs、Mg-Al LDHs、Co-Al LDHs系列水滑石,通过X射线衍射(XRD)、傅里叶红外光谱(FT-IR)、热重-差热分析(TG-DTA)等表征手段对上述样品进行分析和表征。结果表明:采用低饱和共沉淀法制备的上述水滑石结晶度较高,结构规整,具有良好的层状结构和热稳定性。更多还原

【Abstract】 The Zn-Al LDHs、Mg-Al LDHs and Co-Al LDHs powders were prepared with low-super-saturation-co-precipitation method.The presented samples were characterized in detail by X-ray diffraction(XRD),infrared spectroscopy(FT-IR) and thermo-gravimetric differential thermal analysis(TG-DTA).The results showed that the above series of hydrotalcite by low-super-saturation-co-precipitation possessed high crystallinity,overall plan,good layered structure and thermal properties.更多还原
