Exhaust gas purification device for internal combustion engine |
| abstract |
An object of the present invention is to provide an exhaust gas purification apparatus for an internal combustion engine that is used for exhaust gas purification and has both high catalytic activity at low temperatures and high durability at high temperatures. In the exhaust gas purification apparatus for an internal combustion engine of the present invention, a catalyst is disposed in the exhaust path of the internal combustion engine, at least one of the catalysts is noble metal-supported silicon carbide particles, and the noble metal-supported silicon carbide particles have an average primary particle size of 0. It is characterized in that a silicon oxide layer carrying noble metal particles is provided on the surface of silicon carbide particles of 005 μm or more and 5 μm or less. |
