Fig. 1

a Powder X-ray diffraction (PXRD) patterns of the synthesized catalysts. b Transmission electron microscope (TEM) image and selected area electron diffraction (SAED) of Co–B/Ru12. The SAED patterns show the presence of metallic Ru. c EELS spectrum of Co–B/Ru12. Backgrounds of zero-loss peak and plasma peaks have been subtracted. d EDX element mapping of Co–B/Ru12 and the corresponding EDX line scan along the designated arrow. e HR-TEM image of Co–B/Ru12. The purple-colored rectangle symbolizes the crystalline part, while the orange color signifies the amorphous part. f EDX line-scan of Co–B/Ru12 (parallel mode) along the arrow shown in e. Source data for this figure are provided as a Source Data file.
