· JVASP-142453· CoSeS

CoSeS is a cobalt selenide sulfide compound that belongs to the family of transition metal chalcogenides. This material is primarily investigated in research contexts for its semiconducting and catalytic properties, particularly in electrochemistry and energy conversion applications. It is notable for its potential to replace precious metal catalysts in hydrogen evolution and oxygen reduction reactions, making it of interest where cost-effective catalytic performance and earth-abundant materials are prioritized.
