摘　　要：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。by using NH4HCO3 solution and MgCl2·6H2O solution as the precursor,MgCO3·3H2O were prepared via a typical micro-emulsion homogeneous precipitation method.The effects of different surfactants on the morphology of the product were investigated.The results show that sodium dodecyl benzene sulfonate(SDS)as an anionic surfactant has the best effect.MgCO3·3H2O with even size and smooth surface is gained.In addition,the product was texted through FESEM,FTIR,TGA,and XRD.Based on this template,TiO2 microtubes were obtained successfully.
