摘要 报道了一种获得自组装镍球的简单方法,丁二酮肟在镍球的合成中起到了非常关键的作用.所获得的镍球表现出非常大的矫顽力,具有重要的应用前景.同时,这种低温合成方法有望用来制备其他的过渡金属及其合金. We report a rational synthesis of self- assembly metallic nickel spheres by a convenient hydrothermal method, and demonstrate a novel, feasible, and large-scale synthesis of metallic nickel microstructures. The presence of diacetyldioxime was found to play an important role in the formation of spheral structure. The as-synthesized Ni spheres show remarkably enhanced coercivity. Since the formation of a relatively stable complex is universal for various transition metals, we believe such a rational low-temperature synthetic route may be versatile and can be adapted for the fabrication of other transition metals or their alloys.
