In this paper, an efficient microwave-assisted homogeneous synthesis approach by urea hydrolysis is used to synthesize cobalt-basic-carbonate compounds. The dimensions and morphology of the synthesized precursor compounds are tailored by changes in the incorporated anions (CO32- and OH-) under different conditions of temperature and time under microwave irradiation. The wire-like cobalt-basic-carbonate compound self-assembles into one-dimensional porous arrays of Co3O4 nanowires constructed of interconnected Co3O4 nanocrystals along the [1 1 0] axis after thermal decomposition at 350 degrees C. The textural characteristics of the Co3O4 products have strong positive effects on their electrochemical properties as electrode materials in lithium-ion batteries. The obtained porous nanowire Co3O4 arrays exhibit excellent capacity retention and rate capability at higher current rates, and their reversible capacity of 600 mAh g(-1) can be maintained after 100 cycles at the high current rate of 400 mA g(-1) (C) 2010 Elsevier B.V.
