    摘要： An exhaust emission control catalyst disclosed herein is equipped with a rhodium catalytic layer and a platinum catalytic layer, and is characterized in that a relationship between a mole average (X) of a Pauling's electronegativity that is calculated as to elements included in the rhodium catalytic layer except platinum group elements and oxygen and a mole average (Y) of a Pauling's electronegativity that is calculated as to elements included in the platinum catalytic layer except platinum group elements and oxygen is 1.30≦X≦1.45 and 1.47≦Y≦2.0. According to this exhaust emission control catalyst, an interlayer transfer of platinum and/or rhodium and the alloying of platinum and/or rhodium are suppressed during use of the catalyst, and high exhaust gas purification performance can be exerted.

    摘要： It is to provide a method for producing a monolithic catalyst for exhaust gas purification, which can effectively perform exhaust gas purification in accordance with the shape of an exhaust manifold of a catalytic converter, and to provide a monolithic catalyst. The monolithic catalyst has a catalyst coat layer in the axial center region of a substrate, which includes the axial center of an exhaust pipe and has a lower end corresponding to a projected plane of the cross-section of the exhaust pipe, in an amount larger than in a peripheral region other than the axial center region of the substrate. The process of forming the catalyst coat layer which has this distribution of coating amount comprises maintaining a slurry for forming the catalyst coat layer in an approximately truncated conical shape, bringing one end of the monolithic catalyst substrate into close contact with a horizontal side of the slurry, and sucking once the slurry from the other end of the substrate.

    摘要： An automobile exhaust gas catalytic converter includes a first catalyst layer; a second catalyst layer located on a downstream side as compared to the first catalyst layer; and a base material on which the first catalyst layer and the second catalyst layer are respectively located. In the exhaust gas catalytic converter, the proportion (LB/LS) of a coating length (LB) of the second catalyst layer from a downstream end of the base material with respect to a total length (LS) of the base material in the exhaust gas flow direction is approximately 50 to 90%, the proportion of an amount of Rh contained in the second catalyst layer with respect to a total amount of Rh contained in the first catalyst layer and the second catalyst layer is approximately 50 to 90% by mass, and the rest of Rh is contained together with Pd or Pt in the first catalyst layer.
