Hierarchical urchin-like hollow spheres (5–8 μm in diameter) assembled by one-dimensional nanowires consisting of many interconnected Co3O4 nanoparticles (10–50 nm) are successfully synthesized. Co(CO3)0.5(OH)·0.11H2O precursors are firstly prepared by a hydrothermal process. The morphological evolu...
