a TEM image. Inset is the size distribution of nanoparticles. High-resolution HAADF-STEM image (b) and the corresponding pseudo-color surface plot (c). d EELS mapping images. The line scanning EELS spectra (e) and the enlarged EELS spectra for the edge of Ru particle (f). Inset in f is the line scanning path in the STEM-HAADF image. g EDS line-scanning profile across the nanoparticle and the corresponding HAADF-STEM image (inset).
