模板导向合成层状纳米结构碳酸钙研究
Template-directed Synthesis of Lamellar Nanostructured Calcium Carbonate
摘要
Abstract
By using anionic surfactant sodium dodecyl sulphonate (SDS) as supramolecular template and Ca(NO3)2 and Na2CO3 as reactants respectively,Lamellar nanostructured CaCO3 was synthesized in ethanol/water and glycol/water medium via reflux method.The influence of ethanol/water ratio and types of alcohol were studied and the synthesis mechanism was analyzed from the perspective of thermodynamics.XRD analysis showed that the products were ordered lamellar nanostructured calcium carbonate,the average recycling period of lamellar structure was about 3.1 nm and the inorganic composition was calcite and aragonite phases;when the ethanol/water ratio increased or the media was glycol instead of ethanol,the self-assembly of the ordered lamellar nanostructure was promoted and the ratio of aragonite phase increased.关键词
