7787-59-9 | Bismuth Oxychloride

Chemical type

• Layered ternary oxide semiconductor
• Indirect band gap material

^[1]

• Semiconductor photocatalyst (bismuth-based oxychloride nanomaterial)

^[2]

Key properties

• Wide band gap (~3.4-3.5 eV), primarily UV-active
• High chemical stability, non-toxicity, and corrosion resistance
• Open crystalline tetragonal structure
• Low electron-hole recombination due to indirect transition
• Layered structure with [Bi₂O₂]²⁺ and Cl⁻ planes

^[1]

• Monoclinic crystal structure
• Nanoscale crystallite size (~5–6 nm)
• Layered 2D nanosheet morphology (high surface area)
• Visible-light-responsive (band gap ≈ 2.67 eV)
• Porous structure (BET surface area ≈ 13.68 m²/g)
• High photocatalytic activity and stability
• Good recyclability (retains ~87% efficiency after 10 cycles)

^[2]

• Photocatalyst for pollutant degradation (e.g., dyes, phenols)
• Component in heterojunctions to extend visible light response
• Environmental remediation and wastewater treatment

^[1]

• Photocatalyst for degradation of organic dyes:
  • Crystal violet (CV) (~100% degradation in 75 min)
  • Methylene blue (MB) (~96% degradation in 105 min)
• Wastewater treatment (especially dye-contaminated industrial effluents)
• Solar-driven environmental remediation
