CoSe

Cobalt selenide (CoSe) is a layered transition metal chalcogenide compound that belongs to the family of metal selenides. It is of primary interest in energy storage and catalysis research rather than structural engineering, where it shows promise as an electrode material and electrocatalyst. CoSe is notable for its two-dimensional layered structure (reflected in its low exfoliation energy), which can be exploited to enhance surface reactivity and ion transport in electrochemical applications, making it an attractive alternative to precious-metal catalysts in some emerging technologies.
