· Bi9S6O7.5

Bi9S6O7.5 is a bismuth sulfide oxide semiconductor compound combining bismuth, sulfur, and oxygen in a mixed-valence structure. This is primarily a research material under investigation for photocatalytic and optoelectronic applications, belonging to the broader family of bismuth chalcogenides known for tunable bandgaps and visible-light activity. Its mixed anionic composition (sulfide + oxide) offers potential advantages over single-phase alternatives for environmental remediation and energy conversion, though industrial-scale adoption remains limited.
