“…The similar trend has been reported previously in the case of Ir-Rh catalyst [36]. Li et al [37] have found that the strong interaction between Pd and Ir supported on TiO 2 improved the catalyst activity in NO x reduction. In the present study, the activity behavior of the catalysts can be explained to be a consequence of interaction between Ir and Pd.…”

“…0.4–1.0 eV toward higher binding energy with respect to the monometallic Pd catalyst was observed, which can be attributed to the charge transfer from Pd to Ir. The observed BEs of 59.8 and 61.0 eV for Ir 4f 7/2 (Figure b) in Ir/Al 2 O 3 correspond to the reported values for pure and oxidized Ir (formed due to the exposure of the catalyst to air) . The Ir 4f 7/2 BE is shifted to lower values in all three Pd–Ir bimetallic catalysts compared with the monometallic analogue.…”

“…On the one hand, the presence of Pd greatly suppressed the oxidation of Ir species during the reaction. On the other hand, the adsorbed hydrogen on Pd sites promoted the removal of adsorbed oxygen species at Ir sites through spill‐over 129…”
