摘要:本文主要研究了通过水热合成法,用MgCl2•6H2O、AlCl3•6H2O、NaOH制备镁铝双层氢氧化物,此种物质拥有独特的层状结构,层片带结构显正电性,层与层之间存在可交换的阴离子,层之间空间可以调控。针对镁铝双层氢氧化物的这种结构,本文做出了通过阴离子进行插层性能的研究。合成MgAl-NO3-LDHs、MgAl-S2O3-LDHs、LDH-SDBS。通过x射线衍射(XRD)、扫描电子显微镜(SEM)等方法对所制取的样品进行检测与分析,得出其相应的特性。及层间距的大小为LDH-SDBS>MgAl-NO3-LDHs>MgAl-S2O3-LDHs。34965 毕业论文关键词:层状双氢氧化物 插层 制备 阴离子 水热合成
Synthesis and intercalation properties of magnesium aluminum double hydroxides
Abstract: This article mainly studied by hydrothermal synthesis method, With MgCl2 • 6H2O, AlCl3 • 6H2O, NaOH prepared magnesium aluminum double hydroxide, Such material has a unique layered structure, Layer of band structure show electropositive, Exchangeable anion between layer and layer, The space between the layers can be regulated. For this structure magnesium aluminum double hydroxides, This paper made a study carried out by anion intercalation properties. Synthesis of MgAl-NO3-LDHs, MgAl-S2O3-LDHs, LDH-SDBS. By x-ray diffraction (XRD), scanning electron microscopy (SEM) and other methods for the preparation of samples for testing and analysis, The corresponding characteristics are obtained. And the size of the layer spacing of LDH - SDBS > MgAl - NO3 - LDHs > MgAl - S2O3 - LDHs.
