· Ca4 Bi2 Sb2 O12

Ca₄Bi₂Sb₂O₁₂ is an oxide semiconductor compound combining calcium, bismuth, and antimony in a mixed-valence structure, belonging to the family of complex metal oxides with potential photocatalytic and electronic applications. This is primarily a research-stage material investigated for photocatalysis, solar energy conversion, and visible-light-driven environmental remediation, where bismuth-containing oxides are valued for their narrow bandgaps and strong light absorption. The material represents an emerging class of sustainable alternatives to traditional semiconductors for water purification and pollutant degradation under ambient lighting conditions.
