· CaTiO2S

CaTiO₂S is an experimental mixed-anion semiconductor compound combining calcium, titanium, oxygen, and sulfur in a single-phase structure. It belongs to the family of perovskite-derived and layered titanate semiconductors being investigated for photocatalytic and optoelectronic applications. Unlike conventional single-anion titanates (TiO₂), the sulfur substitution modifies the bandgap and electronic structure, making it a research candidate for visible-light-driven photocatalysis, hydrogen generation, and potentially thin-film photovoltaic or photochemical devices where extended light absorption is desired.

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
