“…TEM images of the catalysts were used to estimate the average particle size reported in Table 2. The values are in the range of previous reports for Ir supported on Al 2 O 3 [20,21] and carbon [22].…”

“…All the catalysts displayed a peak corresponding to the Ir 4f transition. The Ir/C ratio was also estimated and the values, shown in Table 2 [7,22,23,24 ]. These results indicate that under the reduction conditions employed iridium oxide was fully reduced to Ir 0 on Ir/CNT, Ir/MG and Ir/AC.…”

“…However, the 4f binding energy of Ir in the samples clearly shifted with the annealing temperature or particle size (see Figure 2 and Table 1 ). As the annealing temperature/particle size increased, the binding energy of Ir 4f decreased, which is quite consistent with previous reports from other groups (Kuznetsova et al, 2012 ).…”

“…In the 5% Ir/C catalyst, Date et al [55] observed three components of the Ir 4f 7/2 peak ascribed to the metallic Ir°(60.9 eV) and oxidized species IrO 2 (61.5 eV) as well as IrO 3 (62.21 eV). It is well known that handling Ir catalysts in contact with air even at room temperature resulted in partial oxidation of iridium, especially the iridium nanoparticles [56]. On the other hand, the single Ir 4f 7/2 binding energy of 61.96 eV and 61.54 eV registered for the single-atomic Ir supported on TiO 2 and on graphitic carbon nitride, respectively, has been ascribed to the Ir S?…”
