Abstract
(EN)
A catalyst (C) for exhaust gas purification comprises a three-dimensional structure (10) and a catalytic component layer (20) supported in the three-dimensional structure (10). The average thickness of the catalytic component layer (20) is 15 μm to 200 μm, inclusive, the average particle size of the catalytic component is 2 μm to 10 μm, inclusive, and the coefficient of variation for the catalytic component particle size is 10 or greater but less than 50. The particle distribution of the catalytic component may be 90% to 99.9% inclusive.
