To study the physicochemical properties of supported Pt catalysts, we performed DFT calculations for the supported Pt3 clusters with various oxides. We determined that the chemical potential (µ) of the supported Pt cluster (µPt/MOx) could be described by averaging the µ values of the isolated Pt3 clusters and support oxides without Pt species (µMOx). The proportional value of the molar fraction of supported Pt species (mol%) should be used as the weighted factors for calculation of the average value. As a result, µPt/MOx could be expected to become µMOx for the actual Pt catalysts, because of their low Pt loadings (∼1 wt% ∼ 0.1 mol%).
