NANOFUNCTIONALISED POLYMERIC SUPPORT WITH PHOTOCATALYTIC NANOPARTICLES BASED ON TITANIUM DIOXIDE AND ITS USE AS PHOTOCATALYSTS

摘要

The present invention relates to a support nanofunctionalised with photocatalytic nanoparticles. Said support is preferably a manufactured product. Said support is a support 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. The present invention also relates to a process for preparing the nanofunctionalised support of the invention. The present invention further relates to the 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. Finally, the subject matter of the present invention relates to 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.
