This study explores the electrochemical performance of Ag-doped bismuth ferrite (BFO+Ag) as a novel electrocatalyst for the oxygen evolution reaction (OER). Utilizing a cost-effective hydrothermal method, BFO+Ag nanopowders were synthesized and characterized for their electrocatalytic properties. The incorporation of silver was found to significantly enhance the activity and reduce the overpotential in OER applications. Electrochemical evaluations demonstrated that BFO+Ag electrodes achieve a current density of 10 mA cm-2 at a reduced overpotential of 1.52 V and display improved Tafel slopes, particularly at elevated temperatures. This work positions BFO+Ag as a promising and economically viable alternative to traditional precious metal-based catalysts for energy conversion and storage solutions, emphasizing the potential for future research to optimize performance and explore practical applications
