The design of an efficient cost-effective electrocatalyst that facilitates oxygen evolution reactions (OERs) in alkaline media is vital for present and future generations, with the durability and stability of the catalyst being of paramount importance. Such electrocatalysts are in high demand for renewable technologies, such as solar fuel development and fuel cells, as well as energy storage devices and lithium ion batteries. Herein, we present a simple wet chemical method for synthesizing trimetallic (AuAg/Cu) nanoparticles that can be utilized as an efficient electrocatalyst for OER. The prepared nanocomposite material delivers effective water splitting at a low overpotentials. The OER kinetics of the trimetallic composite material were analyzed experimentally in 1.0 M KOH electrolyte, revealing a Tafel slope of 82 mV/dec corresponding to an overpotential of 300 mV and a resistance of 177.9 Ω. These values provides the functional material for OER activity and can be used for electrochemical water splitting properties due to synergetic effects produced for the development of other functional materials composite material exhibiting excellent stability and durability over the 40 hours test duration. Therefore, this study demonstrates a safe and clean route toward fabricating efficient electrocatalysts comprising mixed-metal alloys that are suitable for renewable energy applications. The proposed synthesis method protocol is cost-effective and simple, and opens a new pathway for the preparation of efficient electrocatalysts.
