AreaThe Centre provides instrument service to other departments and, besides its service activities, it has its own scientific program, the focus of which is applied research. The centre's key research topic is titanium dioxide, which is interesting due to its excellent photocatalytical activity and its various morphological forms with variable particle size. In photocatalytic applications, titanium dioxide is used as a component in active coatings, in the form of crystalline nanosheets or as a composite with SiO2 (protection against biological contamination of building surfaces by algae and fungi, as self-cleaning screeds for concrete surfaces or wood preservatives).For sorption applications, especially in removal of heavy metals and radionuclides from aqueous environment, an amorphous form of titanium dioxide is used, which can also be anchored on recyclable waste.Other examined sorbents are nanocomposites based on graphene and its derivatives, in which e.g. graphene oxide is anchored on polymer substrates, for example, graphene oxide is anchored on polymer substrates. Zeolites and their modified forms, such as metal nanoparticles, metal oxides or ionic liquids, also exhibit high sorption potential. Layered materials are another interesting field of study. Graphene-based materials or double-layered hydroxides are modified with ionic liquids in order to be used as fillers in polymer matrices whose potential is, for example, to improve the mechanical and thermal properties of polymers. Ternary MAX nanolaminates are another type of a layered materials which are interesting for their possible use in extreme conditions including radiation.
