以碳酸氢铵(NH4HCO3)溶液与六水氯化镁(MgCl2·6H2O)溶液为前驱物,采用微乳液均相沉淀法制备了三水碳酸镁纳米棒(MgCO3·3H2O),并研究实验过程中不同类型的表面活性剂对产物形貌的影响。实验结果表明:使用阴离子表面活性剂十二烷基苯磺酸钠(SDS)的效果最好,获得了尺寸均一、表面光滑的MgCO3·3H2O纳米棒。此外,通过FESEM、FTIR、TGA、XRD等表征手段对产物进行检测,并以此为模板,获得了二氧化钛微米管。
(NH4HCO3) solution and magnesium chloride hexahydrate (MgCl2 · 6H2O) solution were used as precursors. The nanometer magnesium carbonate nanometer rods (MgCO3 · 3H2O) were prepared by microemulsion homogeneous precipitation method. The effects of different types of Effect of Surfactants on Product Morphology. The experimental results show that the best performance is obtained by using anionic surfactant sodium dodecylbenzenesulfonate (SDS), and the MgCO3 · 3H2O nanorods with uniform size and smooth surface are obtained. In addition, the products were detected by FESEM, FTIR, TGA, XRD and other characterization methods, and as a template, titanium dioxide microtubes were obtained.
