Abstract

The various issues related to electrocatalysis on bimetallic and alloy surfaces were discussed. The enhanced catalytic activity of bimetallic surfaces were studied with respect to two effects including, the bifunctional effect and the ligand or electronic effect. UHV surface science experiments and first principles calculations indicate that the presence of ruthenium in the platinum surface weakens the bond of carbon monoxide to the platinum. Molecular dynamics simulations of OH adsorbed on a Pt2Ru alloy in presence of water, show that an OH formed on Ru can pick up a hydrogen from a water molecule on a neighboring Pt atom, effectively transferring the OH from Ru to Pt.
