Nanocomposite materials for photocatalytic degradation of pollutants (LIMPID)
Date du début: 1 déc. 2012, Date de fin: 30 nov. 2015 PROJET  TERMINÉ 

Limpid aims at generating new knowledge on photocatalytic materials and processes in order to develop novel depollution treatments with enhanced efficiency and applicability. The main goal of LIMPID is to develop materials and technologies based on the synergic combination of different types of nanoparticles (NPs) into a polymer host to generate innovative nanocomposites which can be actively applied to the catalytic degradation of pollutants and bacteria, both in air or in aqueous solution. Single component nanocomposites including TiO2 NPs are already known for their photocatalytic activities. LIMPID will aim at going one big step further and include, into one nanocomposite material, oxide NPs and metal NPs in order to increase the photocatalytic efficiency and allow the use of solar energy to activate the process. One of the main challenge of LIMPID is to design host polymers, such as hybrid organic inorganic and fluorinated polymers, since photocatalysts can destroy the organic materials. The incorporation of NPs in polymers will allow to make available the peculiar nano-object properties and to merge the distinct components into a new original class of catalysts. At the same time nanocomposite formulation will also prevent NPs to leach into water and air phase, thus strongly limiting the potential threat associated to dispersion of NPs into the environment. Therefore nanocomposites developed in LIMPID will be used as coating materials and products for the catalytic degradation of pollutants and bacteria in water and air, i.e. deposited onto re-usable micro-particles, or in pollutant degradation reactors, and even onto large surfaces, as a coating or paint. In addition such new class of nanocomposites will be also exploited for the fabrication of porous membranes for water treatment. In order to fulfill its objectives, the LIMPID consortium has been designed to combine leading industrial partners with research groups from Europe, ASEAN Countries and Canada.
