Morphological and structural characterizations of 3D GB-Pt scaffolds. (a) FESEM image of 3D GB-Pt scaffolds. (b, c) TEM images of 3D GB-Pt scaffolds with different magnifications. (d, e) HRTEM images of 3D GB-Pt scaffolds, exhibiting clear grain boundaries and -spacing values of 0.223 nm (Pt (111) lattices). The grain boundaries are marked with red lines in (d) and (e). (f) SAED patterns of 3D GB-Pt scaffolds.
