The synthesis and characterization of carbon-coated ferromagnetic nanoparticles that organize into 1-D assemblies of micrometer-sized ferromagnetic chains is described. A controlled aromatization and carbonization of glucose under hydrothermal reaction conditions enabled the preparation of carbonaceous surfactants that were used as shells for the coating of ferromagnetic Fe(3)O(4) nanospheres with a uniform size distribution. Under controlled experimental conditions, it was, for the first time, demonstrated that glucose could be employed as the carbon source in the preparation of continuous 1-D carbon nanoparticle chains with magnetic nanosphere inclusions. The functional groups on the carbon surface will facilitate the linkage of functional groups or catalytic species to the surface in future application. The salient feature of the reported method was the assembly of magnetic nanospheres under hydrothermal reaction conditions in the absence of external fields.
描述了一种将形成微米级铁磁链一维组装的碳包覆铁磁纳米粒子进行合成和表征的方法。在水热反应条件下，葡萄糖的可控芳构化和碳化使得可以制备碳质表面活性剂，该表面活性剂用作具有均匀尺寸分布的铁磁 Fe(3)O(4)纳米球的涂层。在受控的实验条件下，首次证明葡萄糖可以用作连续一维碳纳米粒子链的碳源，其中包含磁性纳米球。碳表面上的官能团将有助于在未来的应用中，将官能团或催化物种连接到表面上。所报道方法的突出特点是在没有外部场的情况下，在水热反应条件下组装磁性纳米球。
