Fig. 5: The HRTEM and STEM characterization of single element and multielement nanoparticles on the Joule heated S-CNFs.
From: Direct observation of the formation and stabilization of metallic nanoparticles on carbon supports
a The HRTEM image of Pt nanoparticles located on edge planes (marked by the red arrows). The carbon basal planes are marked as the yellow dashed circles. The inset shows an enlarged view of a nanoparticle (marked by the red dashed area). b Schematic represents a nanoparticle that is reside on edge plane instead of basal plane in T-graphite. c The ABF-STEM image shows Ru nanoparticles on edge planes, and d the corresponding EDS mapping. e The ABF-STEM image of ternary PdPtNi nanoparticles on edge planes and f the corresponding EDS mapping. All scale bars are 5 nm.
