We synthesized hierarchical coral-like ZnCo2O4 nanowires by a facile surfactant-free hydrothermal method followed by calcination. The coral-like ZnCo2O4 structure was composed of interconnected necklace-type nanowires on the nanoscale, and each nanowire was constructed from small building blocks of primary nanocrystalline nanoparticles. The distinct morphology of the as-prepared coral-like ZnCo2O4 nanowires led to a high surface area and the mesoporosity, resulting in a large number of the electrochemical reaction sites for the redox reaction and facilitated ion transport. Furthermore, the necklace-type nanowires constructed by the interconnected ZnCo2O4 primary nanoparticles accommodated the volume changes during the charge-discharge process. Consequently, the coral-like ZnCo2O4 nanowires exhibited good electrochemical performance when used as an electrode material for the supercapacitors.
