The effect of the size of surface Pd island ensembles on electron transfer of adsorbed perchlorate ions on Au(111)†
Abstract
A progressive increase in the size of Pd ensembles on a mica-supported Au(111) single crystal surface can facilitate electron transfer of perchlorate ions at lower anodic potential in CV curves than pure Au(111) due to a strong ligand effect and Pd–Au neighbouring pairs at edge sites render a higher degree of electron transfer.
