RuRuO2F

RuRuO₂F is a mixed-valence ruthenium oxide fluoride ceramic compound containing both ruthenium metal and ruthenium(IV) oxide phases with fluorine substitution. This is a research-stage material studied primarily for electrochemical and catalytic applications where the unique combination of ruthenium's redox activity and fluorine's electronegativity offers potential advantages over conventional oxides. The material belongs to the family of ternary transition metal fluoroxides, which are of interest in energy storage, electrocatalysis, and functional ceramic systems where conventional single-phase oxides cannot achieve the required performance.
