title: Facile and Eco-Friendly Synthesis of Finger-Like Co₃O₄ Nanorods for Electrochemical Energy Storage.
abstract: Co₃O₄ nanorods were prepared by a facile hydrothermal method. Eco-friendly deionized water rather than organic solvent was used as the hydrothermal media. The as-prepared Co₃O₄ nanorods are composed of many nanoparticles of 30-50 nm in diameter, forming a finger-like morphology. The Co₃O₄ electrode shows a specific capacitance of 265 F g-1at 2 mV s-1in a supercapacitor and delivers an initial specific discharge capacity as high as 1171 mAh g-1at a current density of 50 mA g-1in a lithium ion battery. Excellent cycling stability and electrochemical reversibility of the Co₃O₄ electrode were also obtained.
