摘要:

Flower-like Ni(OH)(2) microspheres were successfully synthesized by a solution growth process with F and NH3 aqueous solutions as Ni2+ coordination agents, and NH3 aqueous solution as Off supplier to accelerate the hydrolyzation of nickel complex species. The microstructure and crystallinity of flower-like Ni(OH)(2) microspheres can be controlled through changing simply solution pH. Uniform flower-like Ni(OH)(2) microspheres made of nanoflakes could be got within 7.5 <= pH <= 8.8. alpha-Ni(OH)(2) was prepared within 7.5 <= pH <= 8.8 and alpha- and beta-Ni(OH)(2) were prepared within 8.0<pH <= 8.8. The diameters of flower-like Ni(OH)2 microspheres changed from 0.6 similar to 1.3 mu m with solution pH. Flower-like Ni(OH)(2) microspheres were composed of nanoflakes with thickness of about 60 nm and length changing a lot from 80 to 230 nm with solution pH.
