Summary:In this paper, we report a successful synthesis of porous ZnCo 2 O 4 nanoflakes by a morphology-conserved and pyrolysis-induced transformation of novel hexagonally shaped, highly ordered, and inorganic-organic-inorganic layered hybrid nanodisks. It is shown that the hexagonal hybrid nanodisks are constructed from organic molecule (ethylene glycol)-directed assembly of inorganic bilayers. The assembly mechanism has been established by a number of structural and spectroscopic techniques. The porous ZnCo 2 O 4 nanoflakes have also been tested as a lithium ion battery electrode, showing high capacity and high cyclability. Porous ZnCo 2 O 4 nanoflakes can now be created by thermal decomposition of inorganic-organic-inorganic layered hybrid nanodisks, which, as an anode for lithium ion batteries, have shown high capacity and high cyclability.
