This product (10) for removing pollutants from a fluid includes, on the one hand, a porous body (12) having an outer and inner specific surface (14) and, on the other hand, a metallized layer (16), the thickness of which is at most nanoscale, covering at least part of the outer and inner specific surface (14) of the porous body (12). The metallized layer (16) includes at least a metal (Ag) bonded to the porous body (12) by chemical bonds (18) that result from the action of intramolecular forces. Further, the metallized layer (16) includes silicon (Si) also bonded to the porous body (12) by chemical bonds (18) resulting from the action of intramolecular forces.
