Co9S8
metal· JVASP-9095· Co9S8
Co9S8 is a cobalt sulfide compound that forms part of the cobalt-sulfur metal sulfide family, characterized by mixed-valence cobalt cations bonded with sulfide anions. This material is primarily investigated in research contexts for energy storage and catalytic applications, where its layered crystal structure and variable oxidation states make it attractive as an alternative to precious-metal catalysts and as a component in advanced battery systems. Co9S8 is notable for its potential to reduce reliance on platinum-group metals in electrochemical devices while offering tunable electronic properties through doping or nanostructuring.
