What are the Key Factors Affecting Heterogeneous Catalysis?
1. Surface Area: A larger surface area provides more active sites for the reactions to occur. 2. Particle Size: Smaller catalyst particles generally provide a higher surface area-to-volume ratio, enhancing catalytic activity. 3. Temperature and Pressure: These conditions can significantly affect the activity and selectivity of the catalyst. 4. Poisoning and Fouling: Impurities can adsorb onto the catalyst surface, blocking active sites and reducing activity.
