Abstract

See full text

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.
