Structural and electronic properties of Ag-Pd bimetallic clusters on Al2O3 substrates: A first principles study

► Bimetallic AgmPdn clusters deposited on alumina support. ► Tetrahedron structure of Ag2Pd2 cluster transform into bent rhombus on deposition. ► Overall charge transfer from surface to the deposited cluster. ► Broadening of electronic energy states for deposited AgmPdn clusters.
