What Challenges Exist in Enhancing Catalyst Activity?
Despite the potential benefits, several challenges must be addressed to enhance catalyst activity effectively:
Deactivation: Catalysts can lose their activity over time due to poisoning, sintering, or fouling. Strategies to mitigate deactivation are essential for maintaining long-term performance. Selectivity: Increasing the activity of a catalyst can sometimes lead to reduced selectivity, producing unwanted by-products. Balancing activity and selectivity is a critical challenge. Cost: Many highly active catalysts, such as noble metals, are expensive. Developing cost-effective alternatives without compromising performance is a significant research focus.
