Sunlight- mediated synthesis of silver nanoparticles using honey and its promising anticorrosion potentials for mild steel in acidic environments

We have developed a simple, novel, green, sunlight mediated and economically feasible approach for the synthesis of silver nanoparticles (AgNPs) using a bio-derived product-honey. AgNPs was characterized using UV-Vis absorption spectrophotometer. An intense surface plasmon resonance band at 450 nm in the UV-visible spectrum clearly revealed the formation of the silver nanoparticles. The effect of the synthesized nanoparticles on the corrosion of mild steel in 0.5 M HCl was studied by electrochemical methods. The experimental results suggest that the silver nanoparticle from honey is an effective corrosion inhibitor for mild steel.
