What are the Challenges in Catalysis for Diesel Engines?
Despite the effectiveness of catalytic after-treatment systems, there are several challenges associated with their use in diesel engines. One major challenge is the durability of the catalysts, as they are exposed to high temperatures and a harsh chemical environment. Over time, catalysts can degrade, losing their activity and efficiency. Another challenge is the cost of precious metals such as platinum, palladium, and rhodium, which are commonly used in catalytic converters.
