Abstract:
(EN) In order to provide an exhaust gas purification catalyst that can purify hydrocarbons, carbon monoxide, and nitrogen oxides within exhaust gas at a low temperature, in an exhaust gas purification catalyst according to the present invention, a region (2) including palladium is provided on a three-dimensional structure (1), a first region (3) and a second region (4) are provided on this region (2) in order from a side where exhaust gas flows in toward a side where the exhaust gas flows out, and the concentration of neodymium included in the first region (3) is higher than the concentration of neodymium included in the second region (4).
(FR) Afin de fournir un catalyseur de purification de gaz d'échappement capable de purifier des hydrocarbures, du monoxyde de carbone et des oxydes d'azote à l'intérieur d'un gaz d'échappement à basse température, la présente invention présente un catalyseur de purification de gaz d'échappement dans lequel une région (2) comprenant du palladium est disposée sur une structure tridimensionnelle (1), une première région (3) et une seconde région (4) sont disposées sur cette région (2) dans l'ordre à partir d'un côté où le gaz d'échappement pénètre vers un côté où le gaz d'échappement s'échappe, et la concentration de néodyme inclus dans la première région (3) est supérieure à la concentration de néodyme inclus dans la seconde région (4).
(JA) 排気ガス中の炭化水素、一酸化炭素および窒素酸化物を低温で浄化することができる排気ガス浄化用触媒を提供するために、本発明の排気ガス浄化用触媒は、三次元構造体(1)上にパラジウムを含む領域(2)が設けられ、領域(2)上であって排気ガスが流入する側から流出する側に向けて順に、第一領域(3)と第二領域(4)とが設けられ、第一領域(3)中に含まれるネオジウムの濃度が第二領域(4)中に含まれるネオジウムの濃度に比べて高くなっている。
