Title (EN) CARBON COATED SILICA PARTICLES AND METHODS OF MAKING SAME
(FR) PARTICULES DE SILICE RECOUVERTES DE CARBONE ET LEURS PROCÉDÉS DE FABRICATION
Abstract:
(EN) 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.
(FR) L'invention porte sur des procédés qui utilisent une précipitation homogène d'un métal sur une surface d'une particule afin de préparer des particules de silice qui ont adsorbé le métal sur elles. Dans certains modes de réalisation, les particules de silice qui ont adsorbé le métal sur elles peuvent être utilisées pour préparer des particules de silice recouvertes de carbone. Les particules de silice recouvertes de carbone peuvent être utiles dans un très grand nombre d'applications, y compris l'utilisation comme sorbants en chromatographie.
