The photocatalytic degradation of toluene was carried out on composite titania/silica photocatalysts in a gaseous carberry-type photoreactor equipped with UVA light source. The photocatalyst was immobilized on aluminium sheets protected with three layers of organically modified sol-gel silica. Thin films were structurally characterized and their photocatalytic activity was compared. The results showed that protective silica layer on aluminium not only reduces the deactivation of the photocatalyst but also increases the adsorption of pollutants.

COBISS.SI-ID: 2439419SLONANO 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 L1-4290, was a member of the organizing committee of the SLONANO conference 2012. Vladimir Vrecko (member of the research group in the project L1-4290) was invited to the conference to present TiO2 nanoproducts of Cinkarna Celje company.

COBISS.SI-ID: 3340145TiO2/SiO2 composites prepared from different types of TiO2 (low-temperature prepared and a commercial one from Cinkarna) and different types of porous SiO2 (SBA-15 and KIL-2) were tested for the degradation of toluene as a model VOC (Volatile Organic Compound) pollutant. Thin layers of TiO2/SiO2 composites were coated on aluminium plates. Aluminium plate was first covered with a protection layer of organically modified sol-gel silica. Carberry-type photoreactor equipped with UVA light source was used. The results show better activity of the composites with commercial TiO2.
