Abstract In this paper, carbon fiber paper (CFP) was used as the carrier to prepare low-loading IrO₂-RuO₂/Co₃O₄@CFP catalysts with different Ir/Ru atomic ratios through hydrothermal, in-situ electrochemical displacement reaction, and high-temperature calcination. The microstructure and electrochemical performance of the catalysts were characterized by scanning electron microscope, high-resolution transmission electron microscope, X-ray diffractometer, X-ray photoelectron spectrometer, and electrochemical measurements. The results show that the catalyst with an Ir/Ru atomic ratio of 4∶1 exhibits the optimal oxygen evolution reaction catalytic activity and stability in acidic media. It achieves an oxygen evolution overpotential of 225 mV at a current density of 10 mA/cm² and a Tafel slope of 45.97 mV/dec. Moreover, no obvious performance degradation is observed after continuous reaction for 50 h at a current density of 100 mA/cm². This study can provide design ideas and feasible strategies for the synthesis of low-cost and high-performance acidic oxygen evolution catalysts.
