Scientific Interests

1. High-temperature thermoelectric harvesting of waste heat and renewable energy.

 Rapid development of high-temperature thermoelectric conversion is of special importance for green energy sector, in particular, by enabling self-sufficient technologies for mobile sectors or remote applications, and hybrid solutions involving thermoelectric modules. Among those applications, which are now considered most prospective, some can be highlighted, as conversion of the concentrated solar radiation, combination with photovoltaic systems and heat recovery from automotive exhaust. A broad impact is expected from the use of oxide-based thermoelectrics, provided by their natural abundance, environmental benefits and capability of operating at high temperatures, as an alternative to traditional Bi2Te3, Bi2Se3, PbTe –based thermoelectrics.

The research is mainly focused at oxide thermoelectric materials including donor-substituted strontium titanate-based materials, ZnO-based composites and various layered cobaltites. The main approaches include:

- Defect chemistry engineering, aimed at deliberate creation of the lattice defects, which result in enhanced phonon scattering and higher mobility of the charge carriers.

- Redox-induced nanostructuring and creation of compositional inhomogeneities (core-shell microstructures) for suppressing the thermal conductivity and faster electronic transport at the grain boundaries.

- Laser floating zone processing for oxide thermoelectrics, in order to create unique micro-/nanostructural features, triggering high thermoelectric performance.

 2. Functional porous cellular ceramics for catalytic and separation applications.

  Functional materials with controlled dimensionality and morphology are recognized as an essential part of numerous engineering solutions for energy, food, water and environmental problems. Those possessing large surface areas, tunable pore size, appropriate thermal stability and tailored acid/basic functionalities, allowing modification with catalytically active species, are of particular interest for both technology and fundamental research. Although many catalytic processes and related materials have already been discovered and improved during the last century, still many opportunities exist both for development of new approaches and even for new solutions in mature technologies.

The research is focused on the bulk functionalization of the monolithic cellular ceramics via hydrothermal treatment and relevant catalytic tests. The main approaches include:

- Processing of porous cellular ceramics through emulsification in alumina/spinel suspensions.

- Functionalization of the pores with nanostructured boehmite/g-alumina via hydrothermal treatment.

- In-situ modification of the pores with nanostructured transition metal layers for catalytic applications.

3. Carbon-lean technologies for metal extraction.

Although classical extractive metallurgy is well-established, and energy consumption per tonne of produced steel has been reduced by 50% in recent years, this sector is now facing stronger pressure to lower greenhouse gas emissions, and to comply with stricter international regulations. Thus, from a broad environmental perspective, one seeks new strategies for carbon-lean iron extraction, with emphasis on electrolysis.

The research is focused on less common technologies of direct electrochemical reduction of metal oxides and pyroelectrolysis. The main research directions include:

- Demonstration of the concept for iron pyroelectrolysis in magnesium aluminosilicate melts.

- Electrolytic in-situ reduction of iron oxides and ferrospinels in alkaline medium.

4. Mixed ionic-electronic conductors for high- and intermediate temperature electrochemical applications.

Mixed ionic-electronic conductors (MIECs) have been and continue to be of a strategic interest for various energy conversion applications, chemical production and environmental monitoring. These include fuel cells, oxygen permeation membranes, batteries and sensors. In a solid oxide fuel cell (SOFC) concept, the MIEC materials provide an enhancement of oxygen reduction reaction kinetics at the cathode, thus facilitating lower-temperature operation and enabling faster start-up times, improved stability and easier thermal management. The use of MIEC oxygen membranes has attracted much attention due to simplicity in construction and operation of reactors for partial oxidation of hydrocarbon feedstock. A dense MIEC membrane delivers pure oxygen from air to the hydrocarbon feed stream, driven by the gradient in partial pressure of oxygen across the membrane. The flux of oxygen-related defects (oxygen vacancies or interstitials) is compensated by a flux of electronic charge carriers. The aim to realize high oxygen fluxes through such membranes requires both fast surface oxygen exchange and ion diffusion in the bulk, achievable via structural tuning of the MIEC materials and design of the membrane architecture.

The research is focused both on the development of new materials with enhanced oxygen transport properties and improved thermochemical stability, and conceptual solutions for membrane design. The main research directions include:

- Various substitution approaches for improving ionic transport, oxygen exchange kinetics, redox stability and suppressing the chemical expansion in perovskite- and K2NiF4-type materials.

- Assessment of asymmetric flat and tubular (hollow-fibre) membrane geometries for oxygen separation process.
