Title (EN) CATALYST FOR PURIFICATION OF EXHAUST GAS
(FR) CATALYSEUR POUR LA PURIFICATION DE GAZ D'ÉCHAPPEMENT
(JA) 排気ガス浄化触媒
Abstract: front page image
(EN) Disclosed is an exhaust gas purification catalyst (10) which comprises at least two catalyst layers laminated on each other. The exhaust gas purification catalyst (10) comprises a catalyst layer (11) containing at least Rh and a catalyst layer (12) containing an oxide of at least one member selected from [Fe, Mn, Ni and Co]. The catalyst layer (12) containing an oxide of at least one member selected from [Fe, Mn, Ni and Co] is superposed on the catalyst layer (11) containing at least Rh.
(FR) L'invention porte sur un catalyseur (10) de purification de gaz d'échappement qui comprend au moins deux couches de catalyseur stratifiées l'une sur l'autre. Le catalyseur (10) de purification de gaz d'échappement comprend une couche de catalyseur (11) contenant au moins Rh et une couche de catalyseur (12) contenant un oxyde d'au moins un élément choisi parmi [Fe, Mn, Ni et Co]. La couche de catalyseur (12) contenant un oxyde d'au moins un élément choisi parmi [Fe, Mn, Ni et Co] est superposée à la couche de catalyseur (11) contenant au moins Rh.
(JA)  少なくとも2層の触媒層を積層してなる排気ガス浄化触媒10である。この排気ガス浄化触媒10は、少なくともRhを含む触媒層11と、{Fe, Mn, Ni, Co}から選ばれる少なくとも1種の酸化物を含む触媒層12とを含む。この{Fe, Mn, Ni, Co}から選ばれる少なくとも1種の酸化物を含む触媒層12が、少なくともRhを含む触媒層11よりも上層側にある。
