“Efficacy of datura metel leaf extract on MnSrO2 NPs synthesized using a green method in terms of pollutant reduction and antimicrobial activity.”

Abstract

In this work, we prepared both chemical and biogenic synthesis of MnSrO₂ (0, 5, 20 ml DLE) nanoparticles using datura metel leaf extraction by co-precipitation method and also prepared Sulfadiazine dye for catalytic activity. The applications and properties of green MnSrO₂ nanoparticles have compared and they were characterized via XRD, SEM, FT-IR, EDX, UV–visible, and PL techniques. These nanoparticles showed an 18–8 nm diameter range, which was arranged in a spherical form combined randomly. The evidence from FTIR spectra showed peaks around 492, 487, 483, 655, 606, and 603 cm⁻¹ for the creation of SrMnO₂ NPs. Antibacterial activity of MnSrO₂ (0, 5, 20 ml DLE) was measured by the well-diffusion method against pathogens, Staphylococcus aureus and Klebsiella pneumonia. The photocatalytic activity of the synthesized metal oxide nanoparticles was investigated by UV–visible spectroscopy for Sulfadiazine dye degradation with bare MnSrO₂ NPs, g-MnSrO₂ NPs [5 ml DLE], and g-MnSrO₂ NPs [20 ml DLE] in presence of visible light irradiation.
