“…Today, the increasing worldwide energy demand and environment concerns lead to extensive research into power sources with low pollution and high energy conversion efficiency [1]. Fuel cell technology is one of the most studied fields in this regard due to its unique properties, such as high energy density and relatively clean exhaust [2].…”

“…In contrast, within the potential window used in this work no apparent Cu dissolution current is observed on the stars-like PtCu nanoparticles, this may be ascribed to there are tiny Cu in the stars-like PtCu alloy nanoparticles. Surface Pt oxides generate at electrode potentials of 0.6 V and higher [41]. In the reverse cathodic scan, reduction peaks at around 0.5 V are associated with partial re-reduction of Ptoxides [42].…”

“…bimetallic NPs systems. 20,21 Our previous work 22 also showed that Pt 3 Ni had a higher electrocatalytic specific activity than both Pt 2 Ni and Pt 1 Ni. However, the reports about clear structure−property correlation for the Pt-M bimetallic NPs with varying M amounts are deficient.…”

Carbon supported Pt−Ni nanoparticles (NPs) electrocatalysts with nominal Pt/Ni atomic ratios of 3:1, 2:1, and 1:1, denoted as Pt 3 Ni/C, Pt 2 Ni/C, and Pt 1 Ni/C, respectively, were obtained by a modified polyol process. The structure of Pt n Ni/C (n = 3, 2, 1) electrocatalysts was studied by using an X-ray absorption spectroscopy technique combined with X-ray diffraction and transmission electron microscopy. Significantly, the NPs of Pt 3 Ni/C in air are demonstrated to have a quasi core−shell structure consisting of a core of metallic Pt surrounded by many small NiO x clusters. In contrast, both Pt 2 Ni/C and Pt 1 Ni/C are demonstrated to have an alloy structure with partial oxidation on the surface. Under the atmosphere of H 2 at 393 K, the Pt n Ni/C became the expected bimetallic alloy. At last, we discuss the effect of Ni amount on the structure of Pt n Ni/C and estimate their possible catalytic activity for methanol oxidation reaction. Our results further confirmed that the structure of Pt−Ni NPs can be influenced by Ni amount and this effect may be enlarged by environment effects.
