Comparative study on the diameter distribution of MgO nanowires has been carried out. MgO nanowires could be synthesized by the direct reaction between metallic magnesium and silica, and the obtained nanowires have diameters ranging from 50 to 200 nm and lengths of several hundreds nanometers, exhibiting a straight wire. The diameter can be downscaled to smaller than 50 nm, and the nanowire exhibits a curved and twisted one-dimensional structure with lengths up to several micrometers, when a fine support catalyst was used as the reactant. The diameter-controlled growth mechanism was also explained in this work.
已对氧化镁纳米线的直径分布进行了对比研究。氧化镁纳米线可通过金属镁与二氧化硅之间的直接反应合成，所得纳米线的直径范围为50至200纳米，长度为几百纳米，呈直线状。当使用精细的载体催化剂作为反应物时，直径可缩小至小于50纳米，且纳米线呈现出弯曲和扭曲的一维结构，长度可达几微米。这项工作还解释了直径控制的生长机制。
