摘要：
The core-shell SiO2/Mg(OH)(2) spheres were synthesized under ambient conditions, with the aid of polyethylene glycol (PEG) and sodium dodecyl benzene sulfonate (SDBS) to modify the morphology and dispersion of the products. The solid and hollow core-shell SiO2/Mg(OH)(2) spheres with different morphologies. such as convex-pointed, gyrus-like and honeycombed, controlled by the ratio of silica and magnesium chloride, were obtained and investigated by means of XRD, EDS, TEM and SEM. The formation mechanism of core-shell SiO2/Mg(OH)(2) structure was discussed in detail. (C) 2009 Elsevier B.V. All rights reserved.
