What are the Implications of Aggregation in Catalysis?
The implications of nanoparticle aggregation in catalysis are significant:
1. Reduced Catalytic Activity: Aggregation reduces the surface area available for catalytic reactions, leading to lower activity.
2. Altered Selectivity: The formation of larger aggregates can change the distribution of active sites, affecting the selectivity of the catalyst.
3. Decreased Stability: Aggregated nanoparticles are often less stable and can lead to catalyst deactivation over time.
4. Challenges in Recovery and Reusability: Aggregated nanoparticles are harder to recover and reuse, which can increase the cost and complexity of catalytic processes.
