Abstract: A functionalized cellular elastomer foam, and a use of a cellular elastomer foam as a catalyst substrate. The cellular elastomer foam is formed by supplying a porous cellular elastomer foam with an apparent porosity and having a mean equivalent diameter of the opening of the pores comprised between 100 ?m and 5,000 ?m. The porous cellular elastomer foam is then placed in contact with at least one compound including at least one catechol unit, and polymerizing the compound including at least one catechol unit on the surface of said porous cellular elastomer foam, thereby obtaining a mechanically flexible catalyst substrate that includes the cellular elastomer foam having on its surface an intermediate phase formed from the at least one compound including at least one catechol unit.

Abstract: A method for modifying a cellular polymer foam with apparent porosity, which includes providing a cellular polymer foam with apparent porosity, placing the cellular polymer foam in contact with at least one compound in order to obtain a cellular polymer foam including on the surface thereof an intermediate phase formed from the compound having at least one catechol unit. The foam may be used as a catalyst substrate.

Abstract: The invention relates to a chemical reactor with a nanometric superstructure, comprising at least one member wherein at least one reaction chamber is arranged, and said reaction chamber being filled at least partially with a high specific surface area material having a specific surface area greater than 5 m2/g, and characterized in that said high specific surface area material is selected from nanotubes or nanofibers. These nanotubes or nanofibers are preferably selected in the group consisting of carbon nanofibers or nanotubes, ?-SiC nanofibers or nanotubes, TiO2 nanofibers or nanotubes. They may be deposited on an intermediate structure selected in the group consisting of glass fibers, carbon fibers, SiC foams, carbon foams, alveolar ?-SiC foams, said intermediate structure filling the reaction chamber of said reactor at least partially.
