While existing bifunctional catalysts struggle to balance activity and stability, Ru-based catalysts have emerged as a transformative solution by optimizing electronic structures to facilitate oxygen intermediate adsorption/desorption. This review examines recent advances in Ru-based catalysts, categorizing strategies into composites, compounds, and single-atom supported catalysts. We analyze the roles of compositing, doping, and support engineering in enhancing activity–stability synergy, extracting design principles for each category. Furthermore, we outline key research directions including ultralow Ru loading, multi-site synergy, and corrosion mitigation.
