Structural characterizations of 3D GB-Pt scaffolds, Pt rods, and commercial Pt/C. (a) XRD patterns demonstrating that all peaks can be indexed to fcc Pt, (b) XPS spectra demonstrating that no other impurity elements were observed, and (c) nitrogen adsorption/desorption isotherm of 3D GB-Pt scaffolds, Pt rods, and Pt/C.
