· JVASP-107071· CoNi2S4

CoNi₂S₄ is a ternary sulfide compound combining cobalt and nickel, belonging to the thiospinel family of materials. This compound is primarily investigated in research and emerging applications rather than established industrial production, where its mixed-metal sulfide structure offers tunable electronic and catalytic properties. The material is gaining attention in electrochemistry and energy storage contexts, where cobalt-nickel sulfides show promise as alternatives to precious-metal catalysts and as electrode materials for advanced battery and supercapacitor systems.
