Improved Oxygen-Storage Composite, CeO2/MnFeOy, for 3-Way Catalysts

Caption

A newly developed catalyst from Japan, CeO2/MnFeOy, has both fast release and large storage capabilities for oxygen. Its high performance in the converting rate of NOx, CO, and total hydrocarbon to less harmful materials was comparable to a reference catalyst despite using 30 percent less of the rare earth element, Ce.
