A support nanofunctionalised with photocatalytic nanoparticles made of polymeric material, preferably transparent or translucid, characterised by a nanoroughness, measured by means of an electron microscope, comprised between 10 and 150 nm and a macroroughness, measured by means of an electron microscope, comprised between 100 and 600 μm, wherein said nano and macro-roughness are diffused internally and/or superficially. A process for preparing the nanofunctionalised support is also described. Further, an use of the nanofunctionalised support as a photocatalyst activated by UV and/or visible light, for the decontamination of a fluid, preferably air and/or water, from organic contaminants, bacteria, moulds, odours and a combination thereof is described. Finally, a filtration device comprising at least one nanofunctionalised support of the invention associated with at least one source of UV and/or visible light configured to irradiate said at least one nanofunctionalised support is described.

Nanofunctionalised polymeric support with photocatalytic nanoparticles based on titanium dioxide and its use as photocatalysts

Described is a device () for reducing pollutants in a gaseous mixture comprising: •a containment body () having an inlet portion () for the gaseous mixture and an outlet portion () for the gaseous mixture, the containment body () imposing on the gaseous mixture a fixed direction of flow (D), •at least one filtering unit () comprising a photocatalytic filter () interposed, along the fixed direction of flow (D), between a first light source () and a second light source (), both having a wavelength in the visible spectrum (400-700 nm), the photocatalytic filter () comprising a photocatalytic nanoparticle coating and the nanoparticle coating comprising titanium dioxide doped with a nitrogen doping agent. •a unit () for straightening the flow before the filtering unit ().

Device for reducing pollutants in a gaseous mixture

The invention relates to a photocatalyst that is active under irradiation with UV light, visible light and sunlight, comprising a powder or a ready-to-use nanometric suspension of nitrogen-doped TiO, wherein the brookite crystalline phase is also present and whose doping nitrogen content (% by weight) is sufficient to ensure photocatalytic activity in the visible region. The photocatalyst can be easily applied to substrates of varying nature.

Nitrogen-doped TiO2 nanoparticles and the use thereof in photocatalysis

A nano-functionalized support comprises an application surface and a photocatalytic nanoparticle coating deposited on the application surface. The photocatalytic nanoparticle coating comprises titanium dioxide doped with a nitrogen-containing doping agent.
