  • Preparation Method of Composite Silica Nanoparticles with Monodispersity
    Publication number: 20100297545
    Abstract: The present invention provides a preparation method of composite silica microparticles with monodispersity, comprising the steps of: (a) adding at least one precursor selected from a titania precursor and an alumina precursor, and a silica precursor to a solvent, which are hydrolyzed to form composite silica microparticles; (b) drying and calcining the composite silica microparticles; and (c) hydrophobically treating the calcined composite silica microparticles.
