Synthesis and Photocatalytic Properties of One-Dimensional Composite Bi₂O₃-Bi₂CrO₆ Nanowires

Figure 6

Photodecomposition of MB dye in solution (20 mg/L) over Bi₂O₃-Bi₂CrO₆ composite nanowires, commercial available Bi₂O₃ and fabricated Bi₂O₃, under visible-light irradiation (𝜆≥400 nm). 𝐶 is the concentration of MB dye at time  𝑡, and 𝐶₀ is the original concentration before it is irradiated.
