| 摘 要： | 以阴离子表面活性剂十二烷基磺酸钠(SDS)为超分子模板,以Ca(NO_3)_2和Na_2CO_3为反应物,在乙醇/水和乙二醇/水体系中制备了层状纳米结构碳酸钙。研究了乙醇/水比例和醇种类的影响,并对合成机理从热力学角度进行了分析。XRD分析表明:产物为有序层状纳米结构的碳酸钙,层状结构的重复周期平均值为3.1 nm,产物无机相的组成为方解石相和文石相。乙醇比例的增加或乙二醇代替乙醇均能够促进有序层状纳米结构的自组装并提高文石相碳酸钙的比例。

| 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. |
