· Ca2 Bi4 O12

Ca₂Bi₄O₁₂ is an oxide semiconductor compound composed of calcium, bismuth, and oxygen, belonging to the family of mixed-metal oxides with potential photocatalytic and optoelectronic properties. This material is primarily investigated in research contexts for photocatalysis, photoelectrochemistry, and potentially visible-light-driven applications, where bismuth-containing oxides are valued for their narrow bandgaps and strong light absorption. It represents an emerging alternative to conventional wide-bandgap semiconductors, with potential advantages in water splitting, pollutant degradation, or gas sensing under visible light conditions.
