Synthesis of Fe³⁺ Doped Bi₂MoO₆ Nanoplate and its Performance on Photocatalytic Degradation of Salicylic Acid

Abstract:

Fe³⁺ doped Bi₂MoO₆ photocatalyst was successfully synthesized via a hydrothermal process using Bi (NO₃)₃ and (NH₄)₆ Mo₇O₂₄4H₂O as starting materials. XRD, SEM and UV-Vis absorption spectrum techniques were employed to characterize the phase composition and spectrum properties of the as-synthesized samples. Salicylic acid was selected as a model pollutant to investigate the effect Fe³⁺ doping on the photocatalytic activity of as-synthesized Bi₂MoO₆. The experimental results indicated that Fe³⁺ element doping can enhance the photocatalytic activity of Bi₂MoO₆ photocatalyst. When the amount of Fe³⁺ doped in Bi₂MoO₆ is 0.5%, the photocatalyst exhibits the best photocatalytica activity. The doped Fe³⁺ doped into the crystal lattice of Bi₂MoO₆ photocatalyst act as the electron traps and facilitates the separation of the separation of photogenerated electron-hole pairs due to its electron deficient. Thus, Fe³⁺ doping improve the photocatalytic with great efficiency.
