Electrochemical techniques are gaining increasing popularity for the characterization of nanomaterials (NMs) on modified electrode surfaces due to their versatility, rapidity, user-friendliness, and low cost. But there is a lack of complete guide for the electrochemical characterization of green nanoparticles (NPs) modified electrode surface. In this context, as a model NM, silver (Ag) nanoparticles (NPs) of a particular shape were prepared following a green synthetic route and applied for the modification of a home-made graphite-rod electrode (GRE) surface to study the modified electrode-solution interface by cyclic voltammetry (CV), differential pulse voltammetry (DPV), as well as electrochemical impedance spectroscopy (EIS). Some characteristic electrochemical parameters were calculated, analyzed, and discussed. All the electrochemical data supports the electrocatalytic behavior of green Ag NPs modified electrode.
