What Are the Challenges in Using Catalysts for Emission Reductions?
While catalysts are highly effective, several challenges need to be addressed:
1. Deactivation: Over time, catalysts can become less effective due to fouling, poisoning, or sintering. This necessitates their replacement or regeneration, which can be costly.
2. Cost: Many effective catalysts, particularly those used in automotive catalytic converters, rely on precious metals like platinum and palladium, which are expensive.
3. Complexity: The development and optimization of catalysts require sophisticated understanding and technology, which can be a barrier for widespread adoption in some sectors.
