摘要： When the amount of coating is increased in a two-layer catalyst or the like containing two noble metals in respective different layers, gas diffusivity in the catalyst and use efficiency of a catalytic active site are reduced to thereby reduce purification performance. In view of this, an organic fiber having a predetermined shape is used as a pore-forming material in formation of an uppermost catalyst coating layer of a multi-layer catalyst, to thereby form an uppermost catalyst coating layer having a high-aspect-ratio pore excellent in connectivity and therefore excellent gas diffusivity.
摘要翻译：当在不同层中含有两种贵金属的双层催化剂等中涂布量增加时，催化剂中的气体扩散性和催化活性部位的使用效率降低，从而降低净化性能。鉴于此，在形成多层催化剂的最上层催化剂涂层时，使用具有预定形状的有机纤维作为孔形成材料，从而形成具有高纵横比的最上层催化剂涂层孔隙连通性好，因此气体扩散性极好。
