Abstract

<jats:title>Abstract</jats:title><jats:p>Graphene, a remarkable material known for its exceptional properties, can be efficiently produced through environmentally friendly methods using renewable resources and eco‐friendly solvents. Recent studies have highlighted the potential of leaf extracts as effective reducing and stabilizing agents in converting graphene oxide (GO) to graphene. This paper presents a green and cost‐effective approach for the effective deposition of silver nanoparticles (Ag NPs) onto the reduced graphene oxide (RGO) nanosheets. The process involves the co‐reduction of GO and AgNO<jats:sub>3</jats:sub> in water using <jats:italic>Moringa olifera</jats:italic> leaf extract, resulting in the formation of a nanocomposite termed reduced graphene oxide‐silver (Ag‐RGO). The formation of RGO and Ag NP is confirmed through UV‐visible spectroscopy, XRD, and Raman spectroscopy techniques. TEM images revealed the morphology of the nanocomposite, depicting 2‐dimensional graphene sheets adorned with Ag NPs. FT‐IR analysis confirmed the removal of oxygenated functional groups from GO, indicating graphene formation. The synthesized Ag‐RGO nanocomposite exhibited significant catalytic, antioxidant, and electrochemical properties. This study underscores the utilization of natural ingredients as sustainable alternatives for producing multifunctional graphene‐silver nanocomposites.</jats:p>
