FeNi₂Se₄ is an iron-nickel selenide compound belonging to the transition metal chalcogenide family, characterized by a mixed-valence metal structure with selenium anions. This material is primarily explored in electrochemistry and energy storage research rather than traditional structural applications, where it shows promise as a catalyst material and electrode component for water splitting, energy conversion, and battery systems. Its notable advantage over conventional catalysts and electrode materials lies in its favorable electronic properties and active surface chemistry derived from the synergistic interaction between iron and nickel sites coordinated by selenium.
