CsMoO2S

CsMoO2S is a mixed-anion ceramic compound containing cesium, molybdenum, oxygen, and sulfur—a member of the chalcogenide oxide family designed to combine ionic and covalent bonding characteristics. This material is primarily investigated in research contexts for photocatalytic applications, particularly water splitting and pollutant degradation under visible light, where the sulfur incorporation modulates the bandgap relative to pure oxide analogues. Its layered structure and tunable electronic properties make it notable as an emerging candidate for sustainable energy applications, though it remains largely in the development phase rather than established in high-volume industrial production.
