Abstract

In the present paper, the authors report their work on bio synthesis of silver nanoparticles by aqueous extraction of seeds of Phaseolus vulgaris. These synthesized nanoparticles are characterized by Uv-Vis Spectroscopy, Fourier Transform (FT) infrared spectrometry, Raman Spectroscopy, and XRD, and then evaluated for their corrosion inhibition potential for mild steel in acid media. The results show that the phytochemicals present in the seed extract of Phaseolus vulgaris can act as a reducing agent as well as capping agent for nanoparticles. Silver nanoparticles in the form of silver oxide were confirmed in the XRD study with the average size 15.75 nm and cubic in nature. Corrosion inhibition potential of these particles has been determined by mass loss method. Results show that these particles can inhibit rate of corrosion of mild steel in acid media if the uniform protective layer would be formed on the metal surface, and can be used in industries as a corrosion inhibitor. The Scanning Electron Microscopy image of the mild steel samples with and without Ag2O nanoparticles shows that there is adsorption of nanopaticles on to the metal surface in the presence of acid media.
