Abstract
This was thought to originate from a higher reactivity of the defect-rich Au surface, which plays a fundamental role for the spillover process. Another factor, which has to be taken into account, is the influence of differences in the hydrogen adsorption energies of Pt nanoislands, which are supported on Au(111) terraces and on Au(111)-defect sites. Hence, different electrocatalytic activities can also be due to different hydrogen adsorption energies.
