摘要：

Spinel CoCo2O4 nanotubes and porous nanostructures have been synthesized by a novel hydrothermal method from Co(NO3)(2)center dot 6H(2)O in mixtures of ammonia and cyclohexane at 220 degrees C. The morphology and phase of CoCo2O4 can be controlled by adjusting the experimental parameters that include the Co2+ concentration and the volume ratio of ammonia to cyclohexane. X-ray diffraction and transmission electron microscopy analyses were used to characterize the products. The formation mechanisms of CoCo2O4 nanostructures is proposed in detail. The electrochemical properties of the as-prepared samples have been investigated. (C) 2009 Published by Elsevier B.V.
