摘要：
Titania (TiO2) nanocoating on silica (SiO2) particles was obtained by controlled hydrolysis of titanium alkoxide precursors. Monodisperse spherical silica particles prepared by Stober method were used as the support. Isolated silica particles with uniform titania nanocoating were obtained by reacting appropriate alkoxide and water at ambient temperature. The thickness and uniformity of TiO2 coating were controlled by adjusting the concentrations of reactants and the amount of added SiO2. The samples were characterized using electron microscopy and electrophoresis. The surface coverage was estimated using isoelectric point (IEP) data. (C) 2001 Elsevier Science B.V.
