Ceramic foams with gradient of porosity and gradient of catalytic active(s) phase(s) |
摘要 |
Architecture comprising ceramic or metallic foam, characterized in that the foam has at least one continuous and/or discontinuous, axial and/or radial porosity gradient ranging from 10 to 90% associated to a pore size from 2 ppi to 60 ppi, at least one continuous and/or discontinuous, axial and/or radial concentration of catalytic active(s) phase(s) from 0.01wt% to 100wt%, preferentially from 0.1 to 20wt.%, and in that the architecture has a microstructure comprising specific area ranging between 0.1 to 30 m 2 /g, a grain size between 100 nm and 20 microns and a skeleton densification above 95%. |
