The synergy among Pt, Sn, and Ru, along with the stable intermetallic structure and active surface structure, contribute to the enhanced performance of Ru-Pt3Sn NCs in methanol electroxidation compared to commercial Pt/C.
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.
