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

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.

Nano-functionalized support and production method thereof

There are described new vitreous products having antibacterial properties for application to metal surfaces.
