摘 要:Ni-Co-Mn-Ce oxides hollow spheres with nanoparticles subunits are synthesized by a facile self-templated method. Glycerol is dispersed in isopropanol to form oil-in-isopropanol quasiemulsion microdroplets, which serve as soft templates for the deposition of the Ni-Co-Mn-Ce glycerate shell. The Ni-Co-Mn-Ce glycerate as templates are annealed to form Ni-Co-Mn-Ce oxides hollow spheres. When tested as electrode materials for supercapacitors,these Ni-Co-Mn-Ce oxides hollow spheres manifest desired electrochemical performances.
