What are the Challenges in Catalysis for Exhaust Emissions?
Despite the effectiveness of catalytic converters and SCR systems, several challenges remain:
Catalyst poisoning: Contaminants such as sulfur and lead can deactivate the catalysts, reducing their efficiency. Thermal durability: Catalysts must withstand high temperatures without degrading, which is a significant engineering challenge. Cost: Precious metals like platinum and palladium are expensive, making the catalytic converters costly to produce. Regulatory compliance: Emission standards are becoming increasingly stringent, requiring continuous advancements in catalytic technologies.
