Main research topics:
Synthesis of micro/mesoporous and nanostructured oxides.

Development of methods for functionalization with different organic groups of nanosized mesoporous silica materials with different morphology.

Modification of mesoporous materials with nanosized transition metal/ metal oxide species.

Physicochemical characterization of modified materials (temperature gravimetrical analysis, temperature programmed reduction, infrared spectroscopy, UV-VIS spectroscopy, adsorption methods etc.).

Investigation of catalytic properties of modified nanocomposite materials:

- Methanol conversion to hydrocarbons, hydrogen, CO and methane as a source of alternative ecological fuel from renewable sources and industry supply with gas mixtures;
- Catalytic combustion of different volatile organic compounds (VOCs) for environmental protection;
- Conversion of alkylaromatic hydrocarbons for petrochemical industry;
- Selective oxidation of alcohols and olefins in gas or in liquid phase for the preparation of intermediates for pharmacy and chemical industry.

Investigation of the relation between catalyst composition, structure and catalytic behaviour. Genesis of the catalytic sites and mechanism of the catalytic processes.

Preparation of new drug delivery systems on the basis of mesoporous silicas with different structure, morphology, particle size and surface functionality.

Study on the optimization of the loading capacity and release properties of loaded drugs - antibiotics, glucocorticoids, anti-inflammatory non-steriods and antioxidants.
