Abstract
Among the natural products, plant extracts and gums find a prominent place. The abundant phytochemical constituents of plant extracts and gums possess considerable potential as inexpensive, non-toxic and renewable sources of a wide range of organic chemicals of industrial significance. The present work used Myrrh gum to prepare monodisperse coated silver nanoparticles. The method used is simple, easy, cost effective and environment friendly. In this study, Myrrh was used for the first time as a reducing and stabilizing agent. X-ray diffraction, ultraviolet visible spectra, transmission electron microscopy, and ultrsonic spectroscopy revealed the formation of monodispersed Ag-NPs with a narrow particle size distribution. The electrochemical behaviour of Myrrh and silver nanoparticles on steel in 1 MHCl solution has been studied by potentiodynamic and EIS measurements. The inhibition efficiency increases with the concentration of Myrrh and silver nanoparticles. The results revealed that inhibitive effect of silver nanoparticles with Myrrh significantly improved the inhibition performance, and produced strong synergistic inhibition effect.
