a Illustration of the synthetic strategy proposed in this work (Note: The model diagram of Joule-heating device and tubular furnace was drawn. Refer to our lab instruments). b TEM and c HRTEM images of the as-prepared Ni3FeN-Ruburied. d HAADF-STEM image with atomic resolution of the Ni3FeN-Ruburied (the Ru single atoms were highlighted in red circles). e Elemental mapping and corresponding STEM images of the Ni3FeN-Ruburied.
