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
