Composite material comprising organic-fibers and zerovalent iron nanoparticles and its use as catalyst

摘要

The present invention provides a composite material containing nanoscale zerovalent iron particles, which comprises a fibrous host material and nanoscale zerovalent iron particles (NZVIs) comprising iron and optionally further one or more metals.;The invention further provides a method of preparation of the material containing nanoscale zerovalent iron particles of any one of the preceding claims, wherein a fibrous material is impregnated with an aqueous or C1-C4-alcoholic iron salt solution, said solution optionally containing at least one further metal containing salt, and subsequently the impregnated fibrous material is subjected to reduction to convert in situ the metal ions to nanoscale zerovalent iron particles.;The novel composite materials are useful as filters and/or catalysts.
