What are the Challenges Associated with Metal Clusters in Catalysis?
Despite their advantages, metal clusters face several challenges:
1. Stability: Metal clusters can agglomerate or sinter, leading to a loss of catalytic activity. 2. Protection: Stabilizing agents used to protect clusters can sometimes interfere with their catalytic performance. 3. Scalability: The synthesis of metal clusters in large quantities with uniform properties can be difficult. 4. Characterization: Determining the precise structure and composition of metal clusters is challenging due to their small size.
