Year: 2024

Type: article

Abstract: In this study, GdFeO3 (GFO) and Mn‐doped GFO (Mn/GFO) photocatalysts were prepared via hydrothermal method for photo‐Fenton degradation of methyl orange. Different characterization techniques were employed to confirm Mn was successfully incorporated into the lattice of GdFeO3 perovskite. The influence of Mn doping on the photo‐Fenton catalytic activity of Mn/GFO was also studied. The experimental results showed that the Mn‐doped GdFeO3 photocatalyst exhibited greater photo‐Fenton catalytic performance under visible light irradiation than undoped GdFeO3 sample. Particularly, the methyl orange degradation rate of 10Mn‐doped GdFeO3 could reach up to 97.2%. And the first order kinetic constant of optimized conditions (0.0456 min−1) using 10Mn‐doped GdFeO3 was about 4.97 times than that of pure GdFeO3. Besides, the as‐prepared photocatalyst possessed favorable stability and reusability after four cycles of use. This work presents the potential application of Mn‐doped GdFeO3 in the degradation of dye in visible region.
