Urška Lavrenčič Štangar, invited lecture on the 4th SlovenianCroatian 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: 2038267Among a wide range of pollutants detected in wastewater and polluted air, organic compounds are an important group. Attractive methods for their treatment are advance 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 surfaceof the catalyst plays an important role in adsorption and desorption ofthe 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 is presented with the emphasis on the promisingnewly prepared mesostructured silicate with interparticle porosity.

COBISS.SI-ID: 4654874Contribution 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.
B.03 Paper at an international scientific conference
COBISS.SI-ID: 4749082SLONANO conferences have been organized annually since 2002, so that SLONANO 2012 represents the eleventh in the row. The basic idea of the conference is to foster the rapid exchange of results, ideas and know how in the field of nanotechnology. In particular, young scientists are strongly encouraged to present their work. SLONANO 2012 concentrated on three major topics: 1) Complex soft matter and colloids, 2) Nanoporous structures and materials, 3) Nanotechnology in Biomedicine. Prof. dr. Nataša Novak Tušar, principle investigator of the project L14290, was a member of the organizing committee of the SLONANO conference 2012. Vladimir Vrecko (member of the research group in the project L14290) was invited to the conference to present TiO2 nanoproducts of Cinkarna Celje company.
