· Bi5O7I

Bi5O7I is a bismuth oxyiodide semiconductor compound belonging to the layered perovskite family, combining bismuth oxide with iodide to create a narrow-bandgap material with enhanced visible-light responsiveness. This is primarily a research-stage material being investigated for photocatalytic applications where its bismuth content and iodide doping enable improved light absorption and charge carrier separation compared to conventional TiO2-based photocatalysts. Engineers exploring this material would target applications requiring efficient visible-light activation rather than UV-dependent systems, though it remains in the development phase with limited commercial deployment.

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.
