2D PHOTOCATALYTIC HETERODOMES FOR OXIDATION OF GAS POLLUTANTS
The project “2D PHOTO STRUCTURE” aims at the development of photocatalytic coatings containing heterostructures g-C3N4 / TiO2, for the purification of indoor and outdoor air. Titanium (TiO2) is still the most important photocatalyst, as it shows strong oxidation capacity and physicochemical stability.
NanoPhos in collaboration with NCSR Demokritos, will develop photocatalytic coatings with the addition of new heterostructures. For better contact with pollutants and adequate exposure to radiation, it will also be modified with organic agents.
Armed with the experience and know-how of NanoPhos, special solutions for spraying photocatalytic coatings will be created. Photocatalytic coatings will be tested in laboratory and real conditions. Specially designed spaces of NanoPhos, will be coated with the new materials, in order to make an in-site realistic assessment of their photocatalytic properties and their viability in the market. The activity of the new products for cleaning the air from gaseous pollutants as well as their antibacterial action will be examined.
Achieved Scientific goals
- Synthesis of 2D g-C3N4/TiO2 heterostructures for air pollutant oxidation.
- Incorporation of metallic nanoparticles (Ag) for activity enhancement under indoor light.
- Amphiphilic modification for controlled dispersion in formulations.
- Evaluation of the photocatalytic activity and investigation of the reaction mechanism.
Achieved Technological goals
- Determination of the optimal g-C3N4/TiO2 composition for incorporation in coatings.
