Several common issues can affect the performance and longevity of catalysts:
Deactivation: Over time, catalysts can lose their activity due to factors like sintering, coking, poisoning, and fouling. Selectivity: Achieving high selectivity towards the desired product while minimizing by-products is a significant challenge. Stability: Catalysts must maintain their structure and activity under reaction conditions, which can be harsh and variable. Recyclability: The ability to recover and reuse catalysts without significant loss of performance is crucial for economic and environmental reasons.
