Synthesis of Nickel Hydroxide Nanoribbons with a New Phase:  A Solution Chemistry Approach

Abstract

We report here the successful synthesis of one-dimensional (1D) nanoribbons of nickel hydroxide crystallized in a new phase. This attempt is based on the treatment of freshly precipitated nickel hydroxide with high concentrations of nickel sulfate. The nanoribbons with monoclinic structure had a chemical composition of Ni(OH)1.66(SO4)0.17(H2O)0.29, which was close to that of α-Ni(OH)2. These nanoribbons were very pure single crystals, structurally uniform with typical widths of 5−25 nm, thicknesses of 1−5 nm, and lengths of up to a few micrometers, and could be an ideal system for studying the physical and chemical properties of 1D nanostructured electrode materials.

Controllable Synthesis of Nickel Hydroxide and Porous Nickel Oxide Nanostructures with Different Morphologies

“…[29] Lius group prepared Ni(OH) 2 nanoribbons by hydrothermal treatment of amorphous a-Ni(OH) 2 powder in the presence of high concentrations of nickel sulfate. [26,27] Using an ethanol/water/ ammonia liquor system, Tang et al fabricated Ni(OH) 2 nanobelts, subsequent annealing of which furnished porous NiO nanobelts. [28] However, in spite of the successes menAbstract: a-Ni(OH) 2 nanobelts, nanowires, short nanowires, and b-Ni(OH) 2 nanoplates have been successfully prepared in high yields and purities by a convenient hydrothermal method under mild conditions from very simple systems composed only of NaOH, NiSO 4 , and water.…”

Control of uniform nanostructured α-Ni(OH)2 with self-assembly sodium dodecyl sulfate templates

“…Nevertheless, only few reports successfully control the uniform morphology, e.g. 1-D fiber-like a-Ni(OH) 2 [27,28] and ordered mesoporous a-Ni(OH) 2 [29].…”

Synthesis, microstructures and UV–vis absorption properties of β-Ni(OH)2 nanoplates and NiO nanostructures

“…The b-Ni(OH) 2 nanostructures of various morphologies have been fabricated, such as nanotubes and nanorods by template synthesis [9,10], nanoribbons and nanosheets by hydrothermal treating [11][12][13], and flower-like nanoarchitectures by one-step hydrothermal process with the aid of ethylenediamine [14].…”
