Zn1 Co4 S8

Zn₁Co₄S₈ is a ternary sulfide semiconductor compound combining zinc and cobalt in a fixed stoichiometric ratio, belonging to the thiospinel or related sulfide family. This is a research-stage material primarily investigated for energy storage and electrocatalysis applications, where mixed-metal sulfides show promise as alternatives to precious-metal catalysts and as active materials in electrochemical devices. The cobalt-zinc sulfide composition is notable for potentially combining cobalt's catalytic activity with zinc's cost advantage and stability, making it of interest in the transition toward sustainable energy technologies.
