Catalysts are involved in about 80% of all chemical transformations that we as a society relay on. An efficient and stable catalyst is therefore crucial for obtaining the necessary compounds. Among other measures, the so-called electrification of chemical industry and production of energy sources is an important one to reach goals of green transition. Electro(lysis)reduction plays a key role in these processes. However, not all chemicals and fuels can be obtained using this process. Our group is developing catalysts that enable electrification via magnetic heating of catalysts using an alternating magnetic field. This kind of heating results in a rapid heating of the catalytic layer and its good temperature control. In addition to electrification such reactors enable more flexible production of chemicals and fuels in comparison to conventional heating. Flexibility is especially important for utilization of interment electricity obtained from renewable sources. In the group we develop composite catalysts that contain magnetic nanoparticles and catalytic nanoparticles. We rely on modern analytical methods such as scanning transmission electron microscopy, microanalysis, spectroscopy and magnetometry. In cooperation with experts in the field of catalysis, we strive to understand the influence of key structural and surface properties on the activity, selectivity and stability of catalysts. Key research area that we are active in is the study of influence of magnetic heating on kinetics of chemical reactions leading to development of innovative concepts such as for example conversion of biomass platform chemicals and storage/release of H2 from NH3 and liquid organic hydrogen carriers (LOHC).
