Exhaust Gas Purification Catalyst and Exhaust Gas Purification Method

Abstract

An exhaust gas purification catalyst (C), including a three-dimensional structure (10) and a catalyst component layer (20) supported on the three-dimensional structure (10), where the average thickness of the catalyst component layer (20) is 15 μm or more to 200 μm or less, the average particle size of the catalyst component is 2 μm or more to 10 μm or less, and the catalyst component particle size variation coefficient is 10 or more and less than 50. The particle distribution of the catalyst component can be 90% or more to 99.9% or less.
