AbstractFacile hydrothermal methods have been developed to synthesize large Co(3)O(4) nanocubes, beta-Co(OH)(2) hexagonal nanodiscs and nanoflowers. Samples are thoroughly characterized by field-emission scanning electron microscopy, transmission electron microscopy, X-ray diffraction, Brunauer-Emmett-Teller method, and thermogravimetric analysis. The Co(3)O(4) nanocubes have an average size of about 350 nm with a perfect cubic shape, and the beta-Co(OH)(2) nanodiscs are uniform hexagonal platelets, whereas the beta-Co(OH)(2) nanoflowers are assembled from large sheetlike subunits, After thermal annealing in air at a moderate temperature, the as-prepared beta-Co(OH)(2) samples can be converted into spinel Co(3)O(4) without significant alterations in morphology. We have also Investigated the comparative lithium storage properties of these three Co(3)O(4) samples with distinct morphologies. The nanoflower sample shows highly reversible lithium storage capability after 100 charge-discharge cycles.; Facile hydrothermal methods have been developed to synthesize large Co(3)O(4) nanocubes, beta-Co(OH)(2) hexagonal nanodiscs and nanoflowers.
