In this work, we have synthesized CoCO 3 microaggregation, microcubes and nanoplates by an ionic liquid‐assisted hydrothermal method. The morphologies of the CoCO 3 crystals depend on the concentration of the ionic liquid and the reaction temperature. Moreover, the as‐prepared CoCO 3 crystals can serve as a useful precursor to obtain porous Co 3 O 4 particles with similar morphology by means of calcinations. (© 2012 WILEY‐VCH Verlag GmbH & Co.
