Characterization of PdPt alloys. Electron micrograph images of PdPt alloys, including (a) scanning electron microscopy (SEM) and (b) transmission electron microscopy (TEM). (c) Low-angle X-ray diffraction (XRD) pattern of PdPt with a sharp peak at 2θ = 0.46°. (d) Elemental mapping analysis and (e) line-scan energy-dispersive X-ray (EDX) results of PdPt alloys, with Pd in green and Pt in yellow, respectively. (f) Selected-area electron diffraction (SAED) pattern and (g) high-resolution TEM (HRTEM) of PdPt alloys. The arrows in (g) show the unsaturated Pt atoms. (h) Wide-angle XRD pattern of PdPt alloys, standard Pd (JCPDS: 46-1043) and Pt (JCPDS: 04-0802). Scale bar: (a, b, d, e) 100 nm for SEM, TEM, and mapping results, (f) 5/nm, and (g) 2 nm for HRTEM.
