Bi3 Br1 O4
semiconductor· Bi3 Br1 O4
Bi₃Br₁O₄ is a mixed-valence bismuth oxyhalide compound belonging to the class of layered semiconductors with potential photocatalytic and optoelectronic properties. This material remains primarily in the research phase, investigated for its ability to harness visible light through its narrow bandgap architecture, making it a candidate for photocatalytic water splitting, pollutant degradation, and other light-driven applications where conventional wide-bandgap semiconductors are ineffective. Its bromide-containing structure distinguishes it from more commonly studied bismuth oxides, offering tunable electronic properties that appeal to researchers developing next-generation catalysts and light-absorbing materials.
