What Are the Challenges in Catalysis for Pollution Control?
Despite the effectiveness of catalysts, there are several challenges:
1. Deactivation: Catalysts can become less effective over time due to fouling, sintering, or poisoning by impurities. 2. Cost: Many effective catalysts, such as precious metals, are expensive. 3. Selectivity: Achieving high selectivity for the desired reaction while minimizing by-products is often challenging. 4. Environmental Impact: The production and disposal of catalysts can also have environmental impacts.
