【Abstract】 Hollow microspheres, owing to their unique properties such as low density, high stability etc., have potential applications in the fields of medication, dye, cosmetic, catalyst, and so on. In this paper, hollow nickel microspheres were prepared in ionic liquid 1-butyl-3-methylimidazolium bromide using hydrate hydrazine as reduction agent. The crystal phase and structure of hollow nickel microspheres were characterized by means of powder X-ray diffraction (XRD) and transmission electron microscopy (TEM). The influences of reaction time, concentration of Ni2+ on the hollow structures were investigated, whuich indicated that the formation of hollow spheres maybe follow a corrosive pitting process.更多还原
