Abstract

The current work focusses on the silver nanoparticles (Ag-NPs) that are conveniently green synthesized by Mangifera
indica gum powder extract. The absorbance is measured by UV–Vis spectrophotometer at a wavelength of 455 nm that
represents the Surface Plasmon Resonance of Ag-NPs. Fourier Transform-Infra Red (FT-IR) spectroscopy confirms the
functional groups and reaction mechanisms involved in the green synthesis of Ag-NPs. The elemental analysis of Ag-NPs
is carried out by Energy dispersive X-ray (EDAX) spectrum and its surface morphology was studied by High resolution
transmission electron microscopy (HR-TEM). The average size of Ag-NPs is found to be around 19 nm in diameter. The
crystalline nature of the Ag-NPs is investigated by X-ray diffraction (XRD) and Selected area diffraction (SAED). The AgNPs shows better antioxidant activity against free radicals such as 2,2-diphenyl-1-picrylhydrazyl (DPPH) and superoxide
anion. Ag-NPs effect on reduction mild steel corrosion is examined using non electrochemical methods. It is proved
from experimental tests that the inhibition efficiency increases with increased concentrations of Ag-NPs. The photocatalytic activity of the prepared Ag-NPs under visible light irradiation is assessed by the degradation of methylene blue (MB)
dye.
