It is well known that nanomaterials prepared via mechanochemical routes exhibit a variety of distinct physical and chemical properties that often differ significantly from those of their bulk counterparts. The topic of the doctoral thesis is focused on the preparation of selected types of complex oxides and their high-entropy derivatives using various synthetic approaches, with particular emphasis on mechanochemical processes. Their complex structure predetermines them for specific applications in multiple technological fields. The objective will be the preparation of (nano)materials with potential applications in the energy sector (components of ion batteries, fuel cells, catalysts, etc.).

Their complex structure predetermines them for specific applications in multiple technological fields. The objective will be the preparation of (nano)materials with potential applications in the energy sector (components of ion batteries, fuel cells, catalysts, etc.). Emphasis will be placed on understanding the relationships between chemical composition, structure, and functional properties of the prepared materials. These will be investigated using standard diffraction (XRD), microscopic (SEM, TEM), spectroscopic (FTIR, Raman, UV/Vis, etc.), and electrochemical (CV, EIS, GCD) methods.
