a The schematic illustration of Pd1/ND@G and Pd2/ND@G preparation. Cs-corrected HAADF-STEM images of (b, c) Pd1/ND@G (Scale bar: 2ā€‰nm) and (d, e) Pd2/ND@G (Scale bar: 5ā€‰nm). f, g Enlarged images of Pd2 dimers and their corresponding intensity profiles. Pd K-edge XANES profiles (h) and EXAFS spectra (i) for Pd1/ND@G and Pd2/ND@G (inset: expansion of the highlighted region). j The corresponding XAFS fitting curves for the Pd2/ND@G sample.
