Hierarchical Nanoarchitectures: 3D Hierarchical Co₃O₄ Twin‐Spheres with an Urchin‐Like Structure: Large‐Scale Synthesis, Multistep‐Splitting Growth, and Electrochemical Pseudocapacitors (Adv. Funct. Mater. 19/2012)

Abstract

3D hierarchical Co3O4 twin-spheres and their electrochemical properties are reported by Feng Li, Dianzhen Jia, and co-workers on page 4052. A multistep splitting growth originating from 1D nanorods is proposed to understand the formation of the 3D nanoarchitectures. Supercapacitors fabricated with the 3D materials exhibit excellent performance in energy storage.
