| 摘 要： | 采用共沉淀法合成酸性橙阴离子插层锌铝水滑石(Zn/Al-AO7 LDHs),研究不同pH值及原料金属离子配比对产物结构的影响,利用X射线粉末衍射(XRD),热分析(TG-DTA),傅里叶变换红外(FT-IR)等表征手段,对插层产物的结构进行表征,确定了制备酸性橙插层锌铝水滑石的最适宜条件.用量子化学的B3PW91/6-31G(d,p)方法对Zn/Al-AO7 LDHs模型分子的空间几何构型进行了优化,通过结构组合得到的层间距为2.33 nm,接近XRD测试得到的层间距,从而说明了酸性橙离子在水滑石层板间的排列方式.进一步以甲酰胺为溶剂对水滑石层板进行剥离,得到澄清溶液,根据剥离产物的XRD谱可以确定剥离实验成功.

| Abstract: | Acid orange 7(AO7)-pillared Zn/Al layered double hydroxides(Zn/Al-AO7 LDHs) were successfully synthesized using the co-precipitation method.In this experiment,synthetic parameters such as the pH value and the ratios of raw materials were varied to study their influences on the structure of Zn/Al-AO7 LDHs.Sample characterization was carried out using X-ray diffraction(XRD),thermal analysis(TG-DTA),and Fourier transform infrared(FT-IR) spectroscopy.The molecular geometries of the Zn/Al-AO7 LDHs model were cal... |
