Abstract

Methods using homogeneous precipitation of a metal on a surface of a particle to prepare silica particles having the metal adsorbed thereon are disclosed herein. In certain embodiments, the silica particles having the metal adsorbed thereon can be used to prepare carbon coated silica particles. The carbon coated silica particles can be useful in a wide variety of applications including, for example, for use as sorbents in chromatography.
