“…The enhanced oxygen chemisorption can be attributed to two major factorsenhanced spillover effect by Pt–N/C bonding and heterojunction formation between Pt-MCN and SnO 2 and one minor factor: increased surface area due to FIT structure formation. It has been reported that not only the Pt SAs but also the pyridinic nitrogen site can greatly enhance the oxygen spillover . Specifically, the theoretical studies show that the Pt–N/C site provides a very strong adsorption site for O 2 with the adsorption energy of −1.93 eV, and moreover, the O–O bond length of O 2 adsorbed on the Pt atom is longer than that of O 2 adsorbed on Pt bulk.…”

“…Cobalt moieties bind too weakly to the oxygen molecules with longer bond lengths Co O–O as suggested by DFT-D calculations for efficient oxygen reduction. This adsorbed oxygen on single cobalt atoms with a longer bond is easily broken and reduced to water by a direct four-electron pathway . In addition to these active sites, accessibility of O 2 to these highly active sites is also a vital factor which is achieved by extensive porosity and high surface area allowing a faster mass transport.…”

“…Additionally, a larger peak at 398.6 eV is observed, which is because of the formation of Pt–N bonds (Figure S15c, Table S1). ,,, As shown in Figure a, commercial Pt/C exhibits Pt 4f 7/2 and Pt 4f 5/2 peaks at 71.2 and 74.5 eV, suggesting that Pt mainly exists in the form of Pt 0 . Notably, the Pt 4f peak in Pt 1 /NNGF exhibits stronger peaks for Pt 2+ and new peaks for Pt 4+ . ,, To further probe the electronic structure and coordination environment of Pt 1 at the atomic level, we carried out X-ray absorption of fine structure (XAFS) measurement.…”
