· Bi2O2CO3

Bi2O2CO3 is a bismuth oxide carbonate semiconductor compound composed of bismuth, oxygen, and carbonate groups. It is primarily investigated in photocatalysis and environmental remediation research, where it shows promise for water purification and pollutant degradation under visible light. This layered bismuth compound is notable for its relatively low bandgap compared to many traditional oxide semiconductors, making it attractive as an alternative to titanium dioxide (TiO2) for photocatalytic applications where visible-light activity is critical.

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.
