A simple room temperature solution-phase method has been employed to synthesize beta-Ni(OH)(2) nanoneedles in the presence of a suitable cationic surfactant cetyltrimethylammonium bromide for the first time. The chemical composition and morphology of the as-prepared beta-Ni(OH)(2) nanoneedles were characterized by X-ray powder diffraction and transmission electron microscopy. The effect of surfactant and NH4OH on the morphology and size of beta-Ni(OH)(2) nanoparticles was discussed in detail. The growth mechanism of the as-synthesized nanoneedles was discussed based on the experimental results. The results indicate that the binding between CTAB and beta-Ni(OH)(2) crystal nuclei inhibits crystal growth randomly and favors needle-like single crystal growth with their preferred facets.
