What are the main challenges in using catalysts in chemical reactions?

Some challenges include catalyst deactivation, selectivity issues, and the cost of catalyst materials.

Can you explain catalyst deactivation?

Catalyst deactivation occurs when the catalyst loses its activity due to factors like poisoning, sintering, or fouling.

What can be done to prevent catalyst deactivation?

Preventive measures include optimizing reaction conditions, using protective additives, and regular catalyst regeneration.

Are there specific types of catalysts that are more prone to deactivation?

Yes, heterogeneous catalysts are often more prone to deactivation compared to homogeneous catalysts due to surface interactions.

How does the cost of catalysts impact their use in industry?

High catalyst costs can limit their use, especially in large-scale processes, making cost-effective alternatives desirable.
