Abstract

Abstract Novel, 3D hierarchical Co3O4 twin‐spheres with an urchin‐like structure are produced successfully on the large scale for the first time by a solvothermal synthesis of cobalt carbonate hydroxide hydrate, Co(CO3)0.5(OH)·0.11H2O, and its subsequent calcination. The morphology of the precursor,...
