应用领域

Mesoporous silica particles are used widely in the biomedical field due to their easily tunable structure and composition, diverse surface functionalization properties, and excellent biocompatibility. Our 100 µm silica particles with a pore size ~40A product are suitable for studies as an adsorbents for the removal of contaminants or pollutants from water or air. The porous structure enables efficient adsorption of specific molecules or ions and hence can also be employed in separation processes, such as gas separation or chromatography.[1] Mesoporous silica is also used as a support in heterogeneous catalysis. The particles can be impregnated with noble metals or base metals, for example by treating a suspension of the mesoporous silica with a solution of a precatalyst and activating the catalyst by a treatment such as calcination, reduction, or chemical activation.
