FeFeON2

FeFeON2 is an iron-based ceramic compound containing iron, oxygen, and nitrogen elements, representing a class of mixed-valence iron oxynitride materials. This material family is primarily explored in research contexts for energy storage and catalytic applications, where the combination of iron's redox activity with nitrogen doping offers potential advantages over conventional iron oxides in electrochemical performance and surface reactivity. Iron oxynitrides are of growing interest as alternatives to pure oxides in battery electrode materials and electrocatalysts, where nitrogen incorporation can enhance electrical conductivity and active site density.
