<P>PROBLEM TO BE SOLVED: To provide a foamed metal body for cleaning the exhaust gas of a hybrid car using an internal combustion engine and a motor as power and an exhaust gas cleaning catalyst. <P>SOLUTION: In the foamed metal body for cleaning the exhaust gas of the hybrid car, the skeleton surface of foamed metal is constituted of the foamed metal body coated with an oxidized layer 50-500 nm in average film thickness, the porosity of the foamed metal body is 50-99 volume%, the mean opening diameter of voids opening to the outermost surface of the foamed metal body is 50-600 μm, and the mean aperture ratio of the voids is 15-85 area%. In the catalyst for cleaning the exhaust gas of the hybrid car, the surface of the foamed metal body for cleaning exhaust gas is coated with colloidal particles of a noble metal, for example, platinum. <P>COPYRIGHT: (C)2011,JPO&INPIT |
