In order to study the effect of the cluster composition and the effect of the support, we studied the properties of Pt10 and Pt5Ge5 cluster structures for all supports, except phosphorene. The reason behind these particular compositions is that previously we demonstrated that clusters composed of similar amounts of Pt and Ge are unique since they are significantly more stable than other compositions and they exhibit a remarkable CO poisoning resistance. It should be noted that the Pt10/585-DV and Pt5Ge5/585-DV GM were taken from our previous work. In the particular case of phosphorene, we additionally studied the effects of cluster size and composition in more detail. For this reason, we included the series Pt4-PtGe3, Pt5, Pt6, Pt7 and Pt8-PtGe7. In other words, clusters made of 4-8 atoms with a varying composition (from pure Pt to clusters containing a single Pt atom) were considered.
