· JVASP-121872· CoRuS4

CoRuS4 is a cobalt-ruthenium sulfide compound that belongs to the transition metal chalcogenide family. This material is primarily investigated in research and emerging applications as an electrocatalyst and functional material, particularly valued for its catalytic activity in electrochemical reactions such as hydrogen evolution and oxygen reduction. Its potential advantages stem from the synergistic effects between cobalt and ruthenium components combined with sulfide chemistry, making it an alternative to precious-metal catalysts in energy conversion and storage systems.
