One of the primary challenges in automotive exhaust treatment is the durability of the catalytic materials. The catalysts can degrade over time due to high temperatures and exposure to pollutants. Innovations in catalyst design, such as the development of nanoparticles and new alloy compositions, are helping to improve the lifespan and efficiency of catalytic converters.
Another challenge is the removal of particulate matter (PM) from diesel exhaust. Diesel particulate filters (DPF) are used in conjunction with oxidation catalysts to trap and then burn off the soot particles, reducing PM emissions.
