摘要

In this paper, a facile, one-step hydrothermal method for synthesis of Co(OH)₂ nanodisks and nanorings without using any surfactants is reported. As-prepared samples were thoroughly characterized and analyzed by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), etc. The results showed that the size of as-prepared Co(OH)₂ nanodisks could be determined by controlling the concentration of NaOH (8-16 mM) while maintaining other reaction conditions (such as temperature, reaction time, and solution compositions) unchanged. Furthermore, hexagonal nanorings could be obtained by changing the molar ratio between Ni and Co precursors.
