  • Publication number: 20220280921
    Abstract: A three-dimensional structure (10); and a catalytic component (100) that contains a precious metal complex (22) containing platinum and palladium and a porous material (21), which is supported on the three-dimensional structure (10); where the surface accumulation C (Pt) of the platinum is 0.00070 or more to 0.01000 or less, the surface accumulation C (Pd) of the palladium is 0.00800 or more to 0.10000 or less, the surface accumulation C (Pt) is expressed by C (Pt)=PXPS (Pt)/(d2×PTEM (Pt)×0.01), and the surface accumulation C (Pd) is expressed by C (Pd)=PXPS (Pd)/(d2×PTEM (Pd)×0.01).
