Facile Synthesis of Hollow Nickel Submicrometer Spheres

Facile Synthesis of Hollow Nickel Submicrometer Spheres

Hollow Ni spheres with average diameter of ∼370 nm have been prepared via redox reaction of NiSO4 with NaH2PO2 in a cyclohexane–water–polyglycol emulsion system. It is found that the composition of the reaction system has a significant influence on the formation of hollow Ni spheres. A mechanism of...

Zusammenfassung:Hollow Ni spheres with average diameter of ∼370 nm have been prepared via redox reaction of NiSO4 with NaH2PO2 in a cyclohexane–water–polyglycol emulsion system. It is found that the composition of the reaction system has a significant influence on the formation of hollow Ni spheres. A mechanism of formation of the Ni hollow spheres is proposed.
