Several geometric factors need to be considered in the design of catalysts:
1. Particle Size and Shape: Smaller particles have a higher surface area-to-volume ratio, which can enhance catalytic activity. The shape of the particles also affects how they pack and how reactants diffuse to the active sites. 2. Pore Size and Distribution: The pores in a catalyst must be appropriately sized to allow reactants to reach the active sites while also facilitating the removal of products. 3. Surface Roughness: Increasing the surface roughness can expose more active sites, thereby increasing the catalytic activity.
