Nanoparticulate media for environmental applications

Abstract

The fabrication of non-agglomerated nanoparticulate solids with an open structure is a challenging task in the field of nanotechnology and nanomaterials. Such solids would permit conserving specific size-selected physical and chemical properties and highest specific area of the active phase, by avoiding severe health problems related to undesirably nanoparticles inhalation. We report on a successful preparation of Fe–TiO₂ and Ag,Au–TiO₂ coatings and TiO₂–AlO₃ ultra-porous monoliths with highly reproducible nanoscale morphology for applications in environmental catalysis.
