Notes:
Hollow microspheres of nickel hydroxide and nickel oxide were prepared withas-synthesized PS/Ni(OH)2 composite particles by sacrificing core method, respectively. Thecomposite particles were synthesized by deposition of the Ni(OH)2 nanoflakelets formed by thehydrolysis of nickel nitrate onto the surfaces of polystyrene (PS) particles. The effects of differentconcentrations of nickel salt and urea on the deposition of the nanoflakelets of nickel hydroxidewere studied. It was found that the uniform nanoflakelets were deposited on the polystyreneparticles under the conditions of the 4╳10-3 M nickel salt and 0.667M urea. Compared with thedirectly calcinating of composite particles, Integral hollow microspheres of nickel hydroxide wereattained by removal of cores of polystyrene in composite particles with toluene and NiO hollowmicrospheres by calcinating of these Ni(OH)2 hollow spheres in oven at 600℃ for 2h
