Fumed silica has a wide range of applications in the field of catalysts and exhibits excellent catalytic performance. The following are several common applications of fumed silica in the field of catalysts and some aspects of their catalytic performance:

Catalyst carrier: Fumed silica has a high specific surface area and rich pore structure, which can be used as a catalyst carrier. High-efficiency catalysts can be prepared by introducing active components or catalysts, such as metal particles or transition metal oxides, on the surface of silica. The large specific surface area of silica provides more active surface area for catalytic reactions, and the pore structure provides a good reaction environment and molecular diffusion channels.

Catalyst support material: Fumed silica can be used as a catalyst support material to provide a highly stable catalytic reaction environment. The high temperature stability and chemical stability of silica make it suitable for high temperature or corrosive catalytic reactions.

Catalytic reaction aid: Appropriate addition of fumed silica can improve the selectivity, activity and stability of the catalytic reaction. It can adjust the adsorption performance of reactants and the generation of reaction intermediates, and improve the efficiency and product selectivity of catalytic reactions.

Catalyst regeneration: As a catalyst carrier, white carbon black can be used for catalyst regeneration and recovery. Through the process of adsorption, separation and regeneration, the impurities and accumulations in the catalyst can be effectively removed, and the activity and stability of the catalyst can be restored.
