“…Hence, the Pt 13 cluster with the I h symmetry was employed in this work, although it is not global minima as mentioned by several authors (Wang and Johnson 2007;Kumar and Kawazoe 2008;Longo and Gallego 2006;Chang and Chou 2004). Indeed, this model has been used in previous studies of deposition of Pt 13 clusters to pristine and defective graphenes (Cuong et al 2008;Okamoto 2006;Chi et al 2006). Based on the above discussion, the alloys NPs are then constructed by substituting the Pt atoms with one, two, and three Fe atoms, respectively, forming the Fe 1 Pt 12 , Fe 2 Pt 11 , Fe 3 Pt 10 configurations.…”

Recent experimental studies have shown that the FePt nanoparticles (NPs) assembled on graphene exhibit enhanced durability and catalytic activity for oxygen reduction reaction (ORR) than Pt-only catalysts. In this work, we have performed density functional theory calculations to investigate the stability and reactivity of several Fe n Pt 13-n NPs deposited on defective graphene for ORR, where n is adopted as 0, 1, 2, and 3, respectively. The results indicate that the alloying between Fe and Pt can enhance the stability of NPs and promote their oxygen reduction activity. Moreover, the monovacancy site in the graphene can provide anchoring sites for these bimetallic NPs by forming strong metal-substrate interaction, ensuring their high stability. Importantly, the O 2 adsorption on these composites is weakened in various ways, which is ascribed to the change in their averaged d-band center. Thus, these composites exhibit superior catalytic performance in ORR by providing a balance in the O 2 binding strength that allows for enhanced turnover. Our results may be useful to unravel the high stability and reactivity of defective graphene-FePt NPs for ORR from a theoretical perspective.
