· NbNbO2S

NbNbO₂S is a mixed-valence niobium oxysulfide semiconductor compound combining metallic niobium with oxygen and sulfide anions in its crystal lattice. This is a research-stage material primarily investigated for photocatalytic and electrochemical applications, particularly in energy conversion and environmental remediation contexts where the dual anionic system (oxide and sulfide) can enhance light absorption and charge carrier dynamics compared to simple binary oxides or sulfides.

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.
