1 The proposed research topic concerns an innovative method of hydrogen production from the direct conversion of methane from biogas and other sources to hydrogen and carbon in a microwave catalytic reactor. The European Commission confirmed the actuality of this research topic by a recently announced call within the Horizon Europe framework. WUT is one of the beneficient (Robert Cherbański, PhD, DSc, Assoc. Prof. is the project manager at WUT). The broad scope of the research offers excellent opportunities for scientific development for the person who decides to pursue a doctorate. One of the project's main goals is to develop a technology demonstrator for directly converting biogas into valuable carbon materials and a hydrogen-rich stream. The proposed research topic is closely related to one of the research directions being developed at WICHiP. Previous activity concerned the hydrogen and synthesis gas production using both classical methods (steam and dry reforming) and innovative methods, e.g. obtaining hydrogen with simultaneous CO2 sequestration. In one of the currently implemented projects, the synthesis gas obtained is used to get the fuel of the future, dimethyl ether.
2 The focus of the previously performed studies has been in the field of heterogeneous catalysts in reactions such as ketonization of carboxylic acids and their derivatives, as well as chemoselective transfer hydrogenation of α,β -unsaturated carbonyl compounds, including acrolein and its derivatives. The reaction can be carried out in liquid or vapor phase and is aimed at reducing the environmental fingerprint of organic synthesis due to the elimination of the need to use toxic organic solvents, gaseous hydrogen under pressure and does not lead to the formation of harmful by-products or waste. The future research will be aimed at expanding the knowledge regarding the selective transfer hydrogenation to specific carbonyl groups to obtain commercially interesting and potentially applicable unsaturated alcohols. The catalysts for this reaction will be metal oxides, especially modified MgO due to the basicity of its surface, which is beneficial in catalyzing these reactions. The investigations of the surface properties, the synthesis procedures and their impact on the activity of the obtained systems remains an important aspect of such studies. Various metal oxides exhibit a drastically different activity in the aforementioned reactions, hence several options will be investigated.
3 Design, preparation and characterization of catalysts for large-scale industrial chemical processes of significant economic importance and functional materials used in electromobility, energy storage and production and hydrogen technologies for sustainable development. Current activity is focused around the research, development and implementation of novel, more efficient cobalt catalysts for processes of ammonia synthesis, decomposition and oxidation, where ammonia is used as raw material, fuel or hydrogen carrier.
