In Situ Exfoliation and Pt Deposition of Antimonene for Formic Acid Oxidation via a Predominant Dehydrogenation Pathway

Figure 5

The density functional theory (DFT) calculations. Top and side views of optimized Pt10 cluster on (a) graphene and (c) Sb support. The charge transfers are labeled by red words. Blue, purple, and gray balls present Pt, Sb, and C atoms, respectively. Gray and purple lines denote the graphene and antimonene, respectively. The calculated free energy diagrams for FAOR on (b) Pt/C and (d) Pt/Sb. Blue, white, gray, and red balls present Pt, H, C, and O atoms, respectively. Gray and purple lines denote graphene and antimonene, respectively.
