CoS
metal· JVASP-19651· CoS
Cobalt sulfide (CoS) is an inorganic compound combining cobalt metal with sulfur, classified as a transition metal chalcogenide. It is primarily investigated as an electrocatalytic material and in energy storage applications, where its ability to facilitate electrochemical reactions makes it valuable for hydrogen evolution, oxygen reduction, and supercapacitor electrodes. CoS is notable for offering lower cost and improved catalytic performance compared to precious-metal alternatives like platinum, particularly in alkaline and neutral aqueous environments, though it remains more commonly found in research and pilot-scale applications than in high-volume industrial production.
