· JVASP-107761· FeNiS2

FeNiS2 is an iron-nickel sulfide compound that belongs to the family of transition metal sulfides, potentially exhibiting properties intermediate between metallic and semiconducting character depending on its crystal structure and stoichiometry. This material is primarily of research interest in materials science, with potential applications in energy storage systems, catalysis, and thermoelectric devices where the combination of iron, nickel, and sulfur offers tunable electronic properties. FeNiS2 and related iron-nickel sulfides are investigated as alternatives to precious-metal catalysts and as components in battery electrodes, offering cost advantages and abundant elemental composition compared to conventional materials.
