· MnS2

MnS2 is a manganese disulfide compound that belongs to the metal chalcogenide family, exhibiting layered crystal structure characteristics similar to other transition metal dichalcogenides. While primarily of research interest rather than established commercial use, MnS2 is being investigated for potential applications in energy storage, catalysis, and semiconductor devices due to its tunable electronic properties and layered geometry that enables mechanical exfoliation.
