- Abstract:
-
By examining Pt-core-Ru-shell nanocatalysts of different compositions for the electro-oxidation of methanol, a volcano activity response is revealed according to Ru coverage. This activity profile can be accounted for by a bifunctional mechanism of spilling over the hydroxy species from Ru to Pt in close proximity with supplemental electronic and structural promotions. At high surface coverage of Ru on Pt, it is revealed that a new 'direct' pathway of Ru terraces on Pt sites in close vicinity...
