    • PROBLEM TO BE SOLVED: To provide an exhaust gas-purifying catalyst which achieves an excellent catalystic activity for a long time even at a high temperature or in an oxidation-reduction fluctuation, while reducing the usage of noble metal elements.
      SOLUTION: An exhaust gas-purifying catalyst including hexaaluminate represented by the formula SrAl
      12 O
      19 carrying Pd and Fe is prepared. By using this exhaust gas-purifying catalyst, the interaction of Pd and Fe prevents the lowering of catalystic activity caused by the deterioration of Fe over a long time, and a high catalystic activity can be maintained. As a result of it, when this exhaust gas-purifying catalyst is used, an excellent catalystic activity can be achieved over a long time at a low cost even at a high temperature or in an oxidation-reduction fluctuation while reducing noble metal elements, as Fe can be used as an active ingredient.

    • PROBLEM TO BE SOLVED: To provide a catalyst for recombining hydrogen and oxygen capable of recombining hydrogen and oxygen from a relatively low-temperature state without requiring heating from the outside.SOLUTION: A perovskite-type composite oxide containing a noble metal and an alumina- and/or ceria-based composite oxide are incorporated into a catalyst for recombining hydrogen and oxygen. The catalyst for recombining hydrogen and oxygen can recombine hydrogen and oxygen from a relatively low-temperature state without heating from the outside because it contains a perovskite-type composite oxide containing a noble metal and an alumina- and/or ceria-based composite oxide.

    • PROBLEM TO BE SOLVED: To provide an exhaust gas purifying catalyst capable of effectively demonstrating gas purifying performance as well as reducing usage of noble metal.SOLUTION: The exhaust gas purifying catalyst 1, which includes a first purifying member 2 containing copper and not containing noble metal and a second purifying member 3 arranged adjacent to the first purifying member 2 and containing noble metal, is used for purifying exhaust gas exhausted in a stoichiometric burn area where an air-fuel ratio (A/F) crosses 14.6. As the exhaust gas purifying catalyst 1 includes the first purifying member 2 containing copper and not containing noble metal and the second purifying member 3 containing noble metal, it can efficiently purify the exhaust gas exhausted in the stoichiometric burn area where the air-fuel ratio (A/F) crosses 14.6, and also can reduce the usage of noble metal.

    • PROBLEM TO BE SOLVED: To provide an exhaust gas purifying catalyst capable of developing the excellent catalytic activity of Fe during long-term use under a high temperature or oxidation-reduction change condition while reducing the use of a noble metal element. SOLUTION: Fe is mixed with an oxide containing ceria and/or zirconia to prepare a precursor which is, in turn, baked in an oxidation-reduction atmosphere to obtain the exhaust gas purifying catalyst. Further, in this exhaust gas purifying catalyst, the content of Fe is set to 1-9 wt.%. If this exhaust gas purifying catalyst is used, excellent catalytic activity can be developed at a low cost over a long period of time under a high temperature or oxidation-reduction change condition while reducing the use of the noble metal element because Fe can be used as an active component.
