Abstract:
Oxygen storage components (OSC) based on cerium (Ce) were investigated for their ability to reduce the oxidation temperature of diesel particulate matter (DPM). Among the materials investigated, a cerium-praseodymium (Ce-Pr) composite oxide provided the largest reduction in DPM oxidation temperature. Oxygen isotope tracer experiments revealed that oxygen released from the cerium oxidized the DPM at a lower temperature than the oxygen from the exhaust.
