What Are the Challenges in Using Metal Oxide Surfaces in Catalysis?
Despite their advantages, there are several challenges associated with the use of metal oxide surfaces in catalysis:
1. Deactivation: Metal oxide catalysts can undergo deactivation due to sintering, poisoning, or fouling. This can reduce their activity and lifespan. 2. Selectivity: Achieving high selectivity for desired products while minimizing side reactions is often challenging. 3. Surface Reconstruction: Metal oxide surfaces can undergo structural changes under reaction conditions, which can affect their catalytic performance.
