MoS3

MoS₃ is a molybdenum sulfide compound belonging to the transition metal chalcogenide family, primarily of interest as an emerging catalyst and electrochemical material rather than as a structural metal despite its metallic character. It is investigated in research and development contexts for electrocatalytic applications—particularly hydrogen evolution and oxygen reduction reactions—and shows promise in energy storage and conversion systems where its layered structure and variable oxidation states offer advantages over conventional alternatives like platinum-based catalysts. The material remains largely in the experimental phase, with potential to enable more cost-effective and abundant-element-based catalytic solutions compared to traditional noble metal systems.
