利用水溶性聚乙撑亚胺(PEI)与Co~(2+)和Ni~(2+)配位得到化学计量比可控的镍和钻高分子配合物前驱体,热分解制备了纳米NiCo_2O_4粒子。
The precursor of nickel and diamond macromolecule complexes with controlled stoichiometry was prepared by the coordination of water-soluble polyethylenimine (PEI) with Co 2+ and Ni 2+, and the nanocomposite NiCo 2 O 4 particle.
