A methanol-thermal method has been developed to fabricate one-dimensional composite nanowires by coating multiwalled carbon nanotubes with lanthanum oxide and iron oxide, respectively. The coating structure and composition have been investigated by transmission electron microscopy and the X-ray energy dispersive spectrum. Magnetic measurement for the iron oxide coatings indicated that the coercivity has been enhanced after coating. The method reported here provides a novel procedure for the fabrication of one-dimensional composite nanostructures.
已经开发出一种甲醇热法，通过分别用氧化镧和氧化铁包覆多壁碳纳米管来制备一维复合纳米线。通过透射电子显微镜和X射线能量色散谱对包覆结构和组成进行了研究。对氧化铁涂层的磁性测量表明，包覆后矫顽力有所增强。本文报道的方法为一维复合纳米结构的制备提供了一种新的工艺。
