CATALYST FOR CLEANING EXHAUST

摘要

PROBLEM TO BE SOLVED: To provide a catalyst for cleaning exhaust capable of exhibiting an excellent NOxremoval rate in a hydrogen atmosphere while selectively oxidizing CO present in exhaust.

SOLUTION: The catalyst for cleaning exhaust includes a catalyst for selectively reducing NOxthat contains Pt and selectively reduces NOxpresent in exhaust in a H2atmosphere, and a catalyst for selectively oxidizing CO that includes a composite oxide of a perovskite type comprising Pd represented by formula: A2B2O3and selectively oxidizes CO present in the exhaust.
