· Ba2 Co2 S4

Ba₂Co₂S₄ is a ternary chalcogenide semiconductor compound combining barium, cobalt, and sulfur in a layered crystal structure. This is a research-phase material primarily investigated for photocatalytic and optoelectronic applications, where its bandgap and electronic properties offer potential advantages in energy conversion and photochemical processes. The layered sulfide structure is part of a broader family of transition-metal chalcogenides being explored as alternatives to oxide semiconductors for environments requiring enhanced stability and tunable electronic response.
