Abstract: 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 ?m, wherein said nano and macro-roughness are diffused internally and/or superficially. A process for preparing the nanofunctionalised support is also described.
