摘要：
A Diesel soot catalyst has ceria and platinum present in a Diesel particulate filter in a ratio, by weight, of ceria to platinum of at most about 75. This catalyst allows for the use of very small amounts of platinum metal while still achieving low balance point temperatures for burning of Diesel soot.
