Abstract

In the current paper, we present a systematic calculation based on the Density functional theory (DFT), which aims to highlight the potential effects of doping platinum Pt clusters and the new electronic and light structural characteristics of platinum-infused gold clusters Aun (n= 1-9), so that less energy clusters are selected from the rest of the isomers per cluster size. The most stable structures with the lowest 3D structures starting from n=6. The average length of the bonds between the atoms of each cluster and the binding energy of these clusters is calculated relative to their size. Structural characteristics were studied, discussed and compared with all calculated properties by Gradient Density Approximation (GGA) with the Local Density Approximation (LDA), also highlighted the intensity of calculated cases and comparison of Au2 cluster with PtAu that the grafting of Aun clusters platinum Pt, makes them have characteristics that distinguish them to be qualified in their use of chemical stimulation.
