Figure 1
(a) The SAXS profiles measured for Pt/C and carbon black. The net scattering profile I(Q)Pt for the Pt nanoparticles (circles) is fitted (short-dashed curve) with polydisperse spheres of a Schultz distribution, as shown in the inset. A simulation (long-dashed curve), taking into account the scattering contributions of the carbon black and Pt nanoparticles, is also given for the SAXS data measured at E = 10.353 keV. (b) AWAXS data collected for the Pt/C system. The four dotted lines indicate the four f.c.c. peaks of bulk Pt.
