Photocatalytic degradation of methylene blue dye with biosynthesized Hematite α-Fe2O3 nanoparticles under UV-Irradiation

Desalination and Water Treatment, Journal Year: 2024, Volume and Issue: 317, P. 100079 - 100079

Published: Jan. 1, 2024

Nanoparticles (NPs) are currently extensively utilized in various fields, such as medicine, solar energy, water treatment, and pollution detection. In this study, hematite (α-Fe2O3) NPs were synthesized using a cost-effective environmentally friendly method involving the utilization of biomass filtrate Mentha pulegium bio-reducer. The structural optical properties α-Fe2O3 investigated techniques X-ray diffraction (XRD), UV-Visible spectroscopy, Fourier-transform infrared (FTIR) scanning electron microscopy (SEM). analysis confirmed crystalline nature NPs, with crystallite size ranging from 16.92 to 35.38 nm. exhibited absorption at 290 nm, indicating direct bandgap 3.25 3.90 eV an indirect 2.69 3.59 eV, determined spectra. FTIR revealed peak 486 cm−1, attributed vibration confirming formation nanoparticles. SEM imaging showed that green-synthesized generally hexagonal shape. efficiency biosynthesized was evaluated for rapid degradation Methylene Blue (MB) dye, achieving rate up 78% after 120 min. These findings could serve foundation development highly effective photocatalytic methods may be employed future removal hazardous dyes contaminated water.
