Ruthenium-based electrocatalyst for efficient acidic water oxidation in PEM water electrolysis for H₂ production.

ABSTRACT: Proton exchange membrane (PEM) water electrolysis is a promising and sustainable technology for hydrogen production. Currently, the anode catalysts used in PEM water electrolysis are predominantly iridium-based electrocatalysts, which are extremely precious and scarce. In this study, we report a mixed (Ru-W)O _x catalyst as a promising alternative to iridium-based catalysts. The (Ru-W)O _x catalyst was synthesized using a simple Pechini-Adams method, and its microstructure and electrochemical performance were optimized by controlling the Ru/W doping ratio and the synthesis temperature. Among the synthesized catalysts, the Ru₆W₄O _x catalyst prepared at 400 °C demonstrated the best oxygen evolution reaction (OER) activ
