The XRD patterns of nanoparticles exhibit broad Bragg peaks because of small size, where the contribution of diffuse component provides us with inherent structural information. Therefore, pair distribution function obtained from a Fourier transformation of high-energy XRD data and structure modeling on the basis of diffraction data becomes an essential tool to understand the structure of nanoparticles. This promising tool was utilized to obtain structural information of Pd/Pt bimetallic core/shell and solid-solution nanoparticles, which show much attention due to their improved hydrogen storage capacity and catalytic activity.
