New composite reduces rare earth element usage in three-way catalytic converters

Green Car Congress

The high-performance, three-way catalytic (TWC) converter is one of the workhorses of emissions reduction for gasoline engines. Ce is an essential element in oxygen-storage materials that reversibly stores and releases large amounts of oxygen depending upon the partial oxygen pressure in the gas phase.
