Several factors can influence the surface area of a catalyst, including:
Particle Size: Smaller particles have a higher surface area to volume ratio, providing more active sites for reaction. Pore Structure: The presence of pores increases the surface area. The size, shape, and distribution of these pores can significantly affect catalytic performance. Synthesis Method: The method used to synthesize the catalyst can impact its surface area. For example, sol-gel methods can produce materials with high surface areas and controlled porosity.
