| MERCURY – Mechanochemický výskum chalkogenidov pre využitie v obnoviteľnej energii | |
| Mechanochemical research of chalcogenides for utilization in renewable energy | |
| Program: | SRDA |
| Project leader: | Ing. Bureš Radovan, CSc. |
| Annotation: | This project aims to advance the field of materials science through the mechanochemical synthesis of metal chalcogenides, focusing on innovative methodologies and devices to enhance the efficiency and understanding of mechanically induced self-propagating reactions (MSRs). The first objective involves the mechanical activation of metals and chalcogens to produce fine, flaky, or delaminated precursors, which are crucial for optimizing the surface area and reactivity of starting materials. To complement this, we will develop a transferable device capable of monitoring pressure and temperature during planetary milling with subsecond resolution, providing valuable insights into the milling process and allowing for precise control over reaction conditions. Our investigation will also explore how the properties of selected reagents and milling conditions influence the ignition time of MSRs, aiming to elucidate the conditions that favor the formation of binary and ternary metal chalcogenides (MxCy, where M = Ag, Cu, Co, In, Ni and C = S, Se). Furthermore, we seek to identify the primary driving forces behind ball-free MSRs for selected metal chalcogenides, which will be critical for predicting reaction outcomes and improving synthesis strategies. Finally, we will explore the application potential of the synthesized products in electrocatalysis, particularly for hydrogen evolution reactions (HER). Through these interconnected objectives, this project aspires not only to produce novel materials but also to contribute to a deeper understanding of mechanochemical |

| Development of highly efficient catalysts for the electrochemical production of hydrogen | |
| Program: | VEGA |
| Project leader: | RNDr. Gubóová Alexandra, PhD. |
| Annotation: | The goal of the presented project is the development of highly efficient catalysts based on transition metals,primarily in the form of high-entropy alloys and phosphides for the electrochemical production of hydrogen. Thecatalyst development process will be made more efficient with the help of computer simulations, which will enablethe calculation of theoretical parameters, the identification of active sites and the analysis of the mechanisms ofhydrogen evolution and oxygen evolution reactions for the rational design of electrocatalysts. The fulfillment of the set goals of the project will contribute to the expansion of important knowledge in the field of hydrogentechnologies, but above all it will lead to the efficient production of hydrogen as a potential fuel of the future.Efficient hydrogen production will help to successfully integrate hydrogen infrastructure according to theEuropean "Smart cities" model, which will support the overall improvement of the environment globally. |
