摘要

α- and β-Ni(OH)₂ with three-dimensional (3D) nanostructures were synthesized in a water-in-oil reverse micelle/microemulsion system. The form and shape of Ni(OH)₂ can be readily tuned by adjusting experimental parameters of the reverse micelle/microemulsion system. α-Ni(OH)₂ with dandelion-like nanostructures was obtained in the reverse microemulsion of cetyltrimethylammonium bromide (CTAB)/water/ cyclohexane/n-pentanol with a molar ratio of H₂O to surfactant of 40; β-Ni(OH)₂ phase with flower-like nanostructures was formed in the reverse micelles of the same composition with a molar ratio of H ₂O to surfactant of 10. Electrochemical measurements of the as-synthesized α-Ni(OH)₂ phase showed that the 3D α-Ni(OH)₂ nanostructures exhibited superior cycling reversibility and improved capacity compared with commercial Ni(OH)₂.
