中文摘要：
利用反相胶束结合溶剂热法制备了BaCO3单晶纳米线。该方法中，油酸／正辛烷／水体系中的反相胶柬起到模板作用，引导BaCO3沿一维方向生长，通过X射线衍射（XRD）、扫描电子显微镜（SEM）、投射电子显微镜（TEM）和高分辨电子显微镜（HRTEM）对BaCO3纳米线进行了表征，结果表明，所制备的BaCO3纳米线为均匀的直线形单晶纳米线，直径为80～200nm，长度为几百纳米到几微米。对BaCO3纳米线的形成机理进行了分析。
英文摘要：
Single-crystalline BaCO3 nanowires were successfully synthesized in a reverse micelle modified solvothermal method. The reverse micelle in Oleie acid/n-octane/water system was proved to work as template to guide the growth of BaCO3 along 1-dimension. The samples were characterized with X- ray powder diffraction （XRD）, scanning electron microscopy （SEM）, transmission electron microscopy （TEM）, and high-resolution transmission electron microscopy （HRTEM）. Results show that the BaCO3 nanowires are single-crystalline and have a uniform structure with diameters between 80 and 200 nm and lengths between hundreds of nanometers and several microns. And the formation mechanism of BaCO3 was discussed.
