For the first time, the high entropy, transition metal-based chalcogenides are synthesized. The materials are characterized by the pentlandite structure, exhibiting promising functional properties with regard to multiple possible applications.

The multi-component approach to materials design, together with the adaptation of the processing conditions, is gaining increasing popularity in energy-conversion-oriented applications allowing highly effective catalysts to be obtained.

With electrocatalysis being the very foundation of multiple energy conversion technologies, the search for more effective, and affordable catalysts is becoming increasingly important for their further development.
