采用碳热蒸发法制备了管状氧化镁纳米晶。在氧化镁和碳的混合物中加入氧化镓。氧化镓被碳还原生成高温下的镓蒸气。凝聚的镓液滴催化了管状氧化镁纳米结构的原位各向异性生长。用X射线粉末衍射法、扫描电子显微镜和高分辨显微镜对产物进行了表征。所有分析表明，所制备的管状氧化镁纳米结构实际上是单晶。
Crystalline tubular magnesium oxide nanostructures were obtained through carbon-thermal evaporation of a MgO powder. Gallium oxide was added into the mixture of MgO and carbon. The reduction of gallium oxide by carbon resulted in gallium vapor at high temperatures. Condensed gallium droplets catalyzed the anisotropic growth of tubular MgO nanostructures in situ. The products were characterized by X-ray powder diffraction technique, scanning electron microscopy, and high-resolution microscopy. All the analyses indicated that the prepared tubular MgO nanostructures are, in fact, single crystals.
