The reaction of nickel chloride and sodium acetate under solvothermal conditions produced Ni(OH)(2) nanoplatelets, which are self-assembled to form a 3D rose-like morphology. After calcination, NiO nanoplatelets were obtained and inherited the rose-like morphology of Ni(OH)(2) precursor. The influences of PEG and reaction temperature on the size and morphology of NiO were investigated. The functions of PEG on the formation of the NiO nanoplatelets and the self-assembly process were discussed. Moreover, the possible mechanism for the formation of rose-like morphology was proposed. The cyclic voltammetry (CV) measurement showed that as-prepared NiO with a rose-like morphology exhibited a good pseudo-capacitance behavior. (C) 2010 Elsevier B.V. All rights reserved.
