· JVASP-155231· MnFe2S4

MnFe2S4 is an iron-manganese sulfide compound belonging to the thiospinel family of metal sulfides. This material is primarily investigated in research contexts for energy storage and catalytic applications, particularly as a potential electrode material in battery systems and as a catalyst for electrochemical reactions. Its mixed-valence metal composition and sulfide structure make it of interest in next-generation battery chemistries and green hydrogen production, where it offers potential advantages in cost and earth-abundance compared to some conventional transition metal oxides.
