Presentation

Main areas of activity:

- Correlation between solid surface reactivity and adsorption states and structural and electronic properties of solid-gas as well as solid-liquid interfaces
- Various solids (such as mixed oxides, metal and semiconductor single crystals, thin films) are studied by different techniques: work function variation, cyclic voltammetry, spectroscopic ellipsometry, and electron spectroscopy.
- Fractal analysis is utilized to correlate adsorption properties and SEM, TEM, AFM and STM micrographs.
- Adsorption on well-defined oxide surfaces is investigated via ab initio and semiempirical quantum calculations.
- Synthesis of composite materials (with micro and macro pore size, obtained by the incorporation of metallic and organic species or polymers in the molecular sieves structures)
- Characterization and testing of catalytic activity.
- Study of catalytic oxidation on oxidic materials (mixed spinelic oxides, perovskites, zeolites) based on temperature programmed reduction and desorption, chemisorption and various catalytic tests.
- Nonuniformity kinetic models are investigated in relationship to structural sensitivity of catalytic reactions.
- Model nano-sized metal supported catalysts for light hydrocarbon partial oxidation.
