Atomically dispersed Ru in Pt3Sn intermetallic alloy as efficient methanol oxidation electrocatalysts

We successfully fabricate a novel concave nanostructure that is composed of atomically dispersed Ru atoms in Pt3Sn nanoconcaves (Ru–Pt3Sn NCs), which shows enhanced performance in methanol electroxidation compared to commercial Pt/C. This could be ascribed to the stable intermetallic structure and active surface structure, as well as the synergy among Pt, Sn and Ru.
