摘要

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 Tr=620 K) and oxidations (by air at TO-520 K). Electroactivity significantly increases after the oxidation treatment due to the formation of closely contacted domains between c-RuO2 and Pt. (Graph Presented).
