Catalytic converters have been used in the US since the 1970s as a way to clean up pollutants from vehicle exhaust. As cars have become more fuel-efficient, however, they use less energy and the temperature of the exhaust gases is lower, which makes it harder to clean up the pollutants. —Yong Wang.
