· JVASP-9371· ZnCo2S4

ZnCo2S4 is a ternary sulfide compound combining zinc and cobalt in a spinel-like crystal structure, classified as a transition metal chalcogenide. This material is primarily investigated in electrochemistry and energy storage research, where it serves as an electrode material or catalyst for applications requiring high charge-transfer efficiency and tunable electronic properties. Its adoption is driven by lower cost and greater abundance compared to precious-metal catalysts, making it attractive for scaling electrochemical systems, though it remains largely in development phase rather than established industrial production.
