CATALYST FOR EXHAUST NOx CLARIFYING

摘要

PROBLEM TO BE SOLVED: To provide a new catalyst capable of efficiently clarifying exhaust NOx from a diesel engine over a long period of time before it is difficult.

SOLUTION: This exhaust NOx clarifying catalyst is formed by coating a platinum-containing catalyst of an average particle size of 0.3-20 nm with a heat-resistant material to a thickness of 0.3-10 μm.
