· Bi1 O2

Bi₂O₂ is a bismuth oxide semiconductor compound belonging to the family of metal oxides used in photocatalytic and optoelectronic applications. This material is primarily investigated in research and emerging industrial contexts for photocatalysis, environmental remediation, and visible-light-driven applications, where its semiconductor band structure makes it attractive as an alternative to traditional wide-bandgap oxides. Engineers consider bismuth oxides when conventional photocatalysts prove inefficient under visible light or when bismuth's low toxicity and earth-abundance compared to heavy metals are project requirements.

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.
