Study on photocatalytic and antibacterial properties of phase pure Fe₂O₃ nanostructures synthesized using Caralluma Fimbriata and Achyranthes Aspera leaves

This research demonstrates the synthesis of phase pure Fe₂O₃ nanoclusters using Caralluma Fimbriata and Achyranthes Aspera as reducing and stabilizing agents. The structure and physicochemical property of the nanoparticles are characterized by X-Ray diffraction (XRD), Fourier Transform Infrared Spectroscopy (FT-IR), Ultraviolet Diffuse Reflectance Spectroscopy (UV-DRS), Field Emission Scanning Electron Microscopy (FESEM) and High-Resolution Transmission Electron Microscopy (HRTEM) analysis. The HRTEM results reveals that the particle size of C. Fimbriata and A. Aspera treated Fe₂O₃ nanoparticles were found to be ∼25 nm and ∼22 nm, respectively. The photocatalytic degradation and reusable of the green treated Fe₂O₃ Nanoparticles were performed by the photodegradation of Methylene Blue (MB) dye solution under solar light irradiation. In addition, green synthesized Fe₂O₃ nanoparticles assayed against gram-negative bacteria Escherichia coli (E.coli).
