Abstract

Reversible redox reactions: The ruthenium on Pt-Ru/C electrocatalysts shows a reversible transformation (see figure), between RuO₂ and Ru, during repetitive reductions (by hydrogen at T_r=620 K) and oxidations (by air at T_O-520 K). Electroactivity significantly increases after the oxidation treatment due to the formation of closely contacted domains between c-RuO₂ and Pt. (Graph Presented).
