PARTICULATE FILTER PROVIDED WITH CATALYST AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a particulate filter provided with a catalyst, which allows a PM (Particulate matter) deposited on the particulate filter to be efficiently and promptly burned by preventing a catalyst metal from being poisoned by S (Sulfur).SOLUTION: A catalyst layer 22 provided at an exhaust gas passage wall 21 of a particulate filter contains a PdPt alloy carrying ZrCe-based composite oxide in which an alloy 24 of palladium (Pd) and platinum (Pt) is carried as a catalyst metal on a ZrCe-based composite oxide 23 containing zirconium (Zr) and cerium (Ce).
