WebFeb 4, 2024 · Ruthenium-based catalyst is one of the most active catalysts for oxygen evolution reaction (OER) in acid media. However, the strong bonding between the Ru sites and oxygen intermediates leads to high overpotential to trigger the OER process. Webon Ru and RuO2 anodes is proposed. Oxygen evolution overpotentials of ruthenium and ruthenium dioxide based anodes are among the lowest ever observed (1). Therefore these materials have attracted much attention in recent years as prospective candidates for O2-evolving anodes in hydrogen pro-
