Anchoring Ultrasmall Pt Nanocrystals onto Carbon Nanohorn-Decorated 3D Graphene Networks to Boost Methanol Oxidation Reaction

Figure 2

Morphological and nanostructural analysis of the Pt/CNH-G hybrid. Typical (a, b) FE-SEM, (c–e) TEM, and (f, g) HR-TEM images of the Pt/CNH-G hybrid. (h) HAADF-STEM and the corresponding elemental mapping images reveal the homogeneous dispersion of (i) C, (j) O, and (k) Pt elements in the Pt/CNH-G hybrid.
