This article describes a facile green strategy for preparing the Ni(OH)(2) microsphere assembled by nanoribbons by the template of the squama inner coat of onion at mild condition. The method is simple and effective. The results of SEM show the products are Ni(OH)(2) microspheres with diameters in the range of 500-2,500 nm. The results of TEM show the microsphere is assembly by nanoribbons, with thickness in the range of 30-50 nm. The products were characterized by powder X-ray diffraction, IR, and thermogravimetric analysis. A possible formation mechanism was also proposed.
