CATALYST FOR EXHAUST PURIFICATION, AND EXHAUST PURIFYING DEVICE AND EXHAUST PURIFICATION METHOD USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a catalyst for exhaust purification that shows excellent exhaust purification performance capable of efficiently purifying hydrocarbon even at low temperature.SOLUTION: A catalyst for exhaust purification comprises a conductive complex oxide. The conductive complex oxide is a perovskite type complex oxide represented by the compositional formula: LaSrMnO(where x is the number of 0.02 to 0.50).SELECTED DRAWING: None
