Abstract
Nanoparticles, nanocomposites, and methods for making the nanoparticles and nanocomposites are disclosed. Illustrated methods include preparing a nanocomposite particle by binding a silicate compound to the surface of a core particle in an aqueous suspension, adding a silicate source and an organic surfactant template, and stirring the aqueous suspension to obtain silicate growth. The resultant nanoparticles and nanocomposites have desired mesoporous silicate structure
