· JVASP-11049· MgTi2S5

MgTi2S5 is an intermetallic compound combining magnesium and titanium with sulfur, representing an emerging material in the transition metal chalcogenide family. This compound is primarily studied in research contexts for energy storage and catalytic applications, leveraging the electrochemical activity of titanium sulfides combined with magnesium's low density and cost-effectiveness. While not yet widely commercialized, materials in this family are attracting attention for next-generation battery technologies and as potential catalysts for hydrogen evolution, offering opportunities to reduce reliance on rare-earth elements compared to conventional alternatives.
