Ruthenium is a metal of considerable importance in electrochemical science and technology, serving as a catalyst or co-catalyst material in Pt-Ru alloys for methanol- and reformate hydrogen-oxidation in fuel cells. This study aims to elucidate the role of ruthenium in enhancing catalytic processes, especially focusing on the mechanisms of its action which are not fully understood. Employing a methodology that includes the examination of both bare and Pt-modified well-ordered Ru(0001) and Ru(10 1 0) single-crystal surfaces, we review the recent progress in understanding structural sensitivity in electrochemistry and electrocatalysis. Significant advancements in model systems have been documented, which clarify the mechanisms underlying Pt-Ru interactions, notably the bifunctional mechanism where Ru provides oxygenated species to oxidize CO blocking Pt sites. Furthermore, we discuss the introduction of a Pt submonolayer on Ru support as a new development in electrocatalyst formulation. Our analysis confirms that ruthenium plays a pivotal role as an electrocatalyst in improving the efficiency of reactions in fuel cells and supercapacitors.
