Developing durable and efficient electrocatalysts for the oxygen evolution reaction (OER) remains a pivotal challenge in advancing anion exchange membrane water electrolysis (AEMWE) for affordable green hydrogen production. In this work, we report a single-step electrodeposition approach to synthesize P-doped bimetallic FeCo catalysts. The optimized catalyst, FeCoP50, demonstrated a low overpotential of 193 mV at a current density of 10 mA cm⁻² under half-cell testing and achieved a high current density of 5.48 A cm⁻² at 2.0 V in an AEMWE cell. Phosphorus incorporation was found to significantly improve both the electrochemical surface area and the intrinsic catalytic properties of the FeCo system. These findings highlight the utility of a one-pot synthesis strategy for enhancing OER performance and underscore the critical role of phosphorus in modulating catalyst structure and activity.
