Contribution on the 5th International FEZA (Federation of European Zeolite Associations) conference (Valencia, Spain): We presented the advantages of immobilization of TiO2 nanoparticles on ordered and disordered mesoporous silicates as high surface area supports in terms of efficiency of this photocatalytic system for decomposition of VOCs.

COBISS.SI-ID: 4749082Urška Lavrenčič Štangar, invited lecture on the 4th Slovenian-Croatian Symposium on Zeolites (Ljubljana, Slovenia): Emission of volatile organic compounds (VOCs) in indoor and outdoor air has become a serious problem causing different degrees of hazard to public health. An overview on the design of TiO2 photocatalytic systems for air cleaning that employ photocatalytic material either in powder or in thin-film form was given. The design of both, photoreactor and photocatalyst, is of a key importance to achieve high efficiency of a photocatalytic system. The promising TiO2 photocatalytic system, which was developed in Laboratory for environmental research at University of Nova Gorica, was presented.

COBISS.SI-ID: 2038267Nataša Novak Tušar - invited lecture on the Slovenian - italian conference on materials and technologies for sustainable growth (Ajdovščina, Slovenia): Among a wide range of pollutants detected in wastewater and polluted air, organic compounds are an important group. Attractive methods for their treatment are advanced oxidation processes (AOPs). Hydroxyl radicals ( OH), highly reactive species generated in sufficient quantities by AOPs, have ability to decompose organic pollutants. Most of AOPs use a combination of strong oxidizing agents (e.g. H2O2, O3) with catalysts (e.g. transition metals) and/or irradiation (e.g. ultraviolet and visible light). Since surface of the catalyst plays an important role in adsorption and desorption of the organic pollutant (e.g. effects on the reaction rate), porous catalysts have an advantage. An overview on the design of catalysts on porous supports for water and air purification was given. The promising newly prepared mesoporous silicate with interparticle porosity, which was recently developed in the Laboratory for inorganic chemistry and technology at the National institute of chemistry, was presented.
