In recent ages, green nanotechnology has gained attraction in the synthesis of metallic nanoparticles due to their cost-effectiveness, simple preparation steps, and environmentally-friendly. present study, copper oxide (CuO NPs) were prepared using Parthenium hysterophorus whole plant aqueous extract as a reducing, stabilizing, capping agent. The CuO NPs characterized via UV-Vis Spectroscopy, Fourier Transform Infrared Spectroscopy (FTIR), powder X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Transmission (TEM), Dynamic Light Scattering (DLS). spectra showed surface plasmonic resonance band occur at 340 nm. FTIR analysis revealed presence secondary metabolites on NPs, with characteristic Cu-O stretching being identified 522 cm

Abstract Today, nanoscience explores the potential of nanoparticles due to their extraordinary properties compared bulk materials. The synthesis metal using plant extracts is a very promising method for environmental remediation, which gets global attention pollution-led warming. In present study, iron (FeNPs) were successfully synthesized by green Vernonia amygdalina leaf extract as natural reducing and capping agent. Biosynthesized FeNPs characterized with different analytical techniques such UV–visible, FT-IR, XRD, SEM. analysis revealed formation amorphous an irregular morphology non-uniform distribution in size shape. average particle was approximately 2.31 µm. According catalytic degradation investigation, produced via approach are highly effective breaking down both CV MB into non-toxic products, maximum efficiency 97.47% 94.22%, respectively, when right conditions met. kinetics study exhibited high correlation coefficient close unity (0.999) (0.995) CV, zero-order pseudo-kinetics model, describes model suitable dyes other models. reusability stability biosynthesized nano-catalysts studied used efficient catalysts slight decrease rate more than four times. results from this illustrate that offer cost-effective, environmentally friendly, means organic dyes.

Abstract The utilisation of ecological materials, such as plant extracts, is a superior alternative to both physical and chemical techniques for the synthesis nanoscale metallic particles. current study concluded that polymer (PVP) Azadirachta indica (A. indica) extract synthesised hematite nanoparticles (HNPs) were spherical, monodispersed, served an agent reducing capping. pure HNPs with most reliable rhombohedral symmetry found be crystalline thanks crisp x-ray diffraction (XRD) reflections. Spheroidal nanostructures formed, seen by scanning electron microscopy (SEM), their composition was validated energy dispersive spectroscopy (EDS) study. At room temperature, antiferromagnetic blocking temperature 300 K. When used catalyst, NPs exposed effective degradation coefficient determination ( R 2 ) toxic Eosin Yellow (EY) Bismarck Brown Y (BBY) dyes in presence UV irradiation. After four consecutive cycles, efficient performance achieved without any evident catalytic loss. Additionally, reusability experiments revealed under direct light illumination, duel-doped may successfully three times. biosynthesised doped from A. leaf demonstrated antioxidant activity through high phenolic flavonoid contents, DPPH radical scavenging activity, reductive potential.
