摘要：

The nearly monodisperse SiO2 submicrospheres with uniform size (270nm) were prepared by the hydrolysis of TEOS. Then the SiO2 submicrospheres were coated with alpha-Ni(OH)(2) nanoflakes by a new solution growth method. The Ni(OH)(2) nanoflakes were synthesized by a solution process using hydrofluoric acid solution as nickel ion ligand to form nickel-fluoro complex, NH3 aqueous solution as OH- supplier and also Supplemental nickel ion ligand. The coating thickness is increased with coating times. It is only 35nm for coating once. After coating three times, the coating thickness is increased to about 100nm. The alpha-Ni (OH)(2) hollow submicrospheres are obtained after subsequent removal of the core particles by NaOH solution (20wt%) at 40 degrees C for 24h. BET calculation shows that the surface area of the Ni (OH)(2) hollow spheres is 141.06 m(2)/g.
