Question: What is the average pore size of the catalyst? What is the effect of pore size on the reaction? Answer: The average pore size of a catalyst is the ratio of the catalyst’s pore volume to its specific surface area, expressed in angstroms (Å). (1 Å = 10-10 meters) The pore size of a catalyst affects not only its activity but also its selectivity. As the specific surface area increases, the pore sizes decrease accordingly. When the molecular diameter of the reactants is larger than the pore size, it becomes difficult for the reactants to diffuse into the pores. Moreover, it is also hard for the intermediate products formed after reaction inside the pores to diffuse out, causing them to remain there and undergo secondary reactions. As a result, unwanted products are generated, which reduces the catalyst’s selectivity.

(1 Å = 10 meters) The pore size of a catalyst affects not only its activity but also its selectivity. As the specific surface area increases, the pore sizes decrease accordingly. Since the molecular diameter of the reactants is greater than these pore sizes, it becomes difficult for the reactants to diffuse into the pores. Moreover, the intermediate products formed after entering the molecular reactor also find it hard to diffuse out, remaining in the pores where they undergo secondary reactions. As a result, unwanted products are generated, reducing the catalyst’s selectivity.

The average pore size is the ratio of the catalyst’s pore volume to its specific surface area. The pore size affects the activity of the catalyst as well as its selectivity. When the specific surface area increases, the pore sizes decrease accordingly; if the molecular diameter of the reactants is larger than these pore sizes, then the reactants have difficulty diffusing into the pores. Moreover, the intermediate products formed after the reaction within the pores also cannot diffuse out, remaining there to undergo further reactions, which results in the formation of unwanted products and a decrease in the catalyst’s selectivity.
