a Schematic diagram of the FMBP experimental setup for synthesis of HEA-NPs. b Schematic diagrams for synthesis of homogeneous and phase-separated HEA-NPs by FMBP and FBP strategies, respectively. c The simulation of the time required for precursors/GO (20 mg, 3 wt%) to reach 923 K in the FMBP process. Center: the metal precursors/GO in the quartz boat. d HAADF-STEM images for the denary (MnCoNiCuRhPdSnIrPtAu) HEA-NPs highly dispersed on GO synthesized by the FMBP strategy (The loading of HEA-NPs on GO was 3 wt%). e The HR-STEM image for the denary (MnCoNiCuRhPdSnIrPtAu) HEA-NPs (inset, the Fourier transform analysis for denary (MnCoNiCuRhPdSnIrPtAu) HEA-NPs indicated that the denary HEA-NPs featured with an fcc crystal framework). f Elemental maps for denary (MnCoNiCuRhPdSnIrPtAu) HEA-NPs (The loading of HEA-NPs on GO was 10 wt%). The elements in HEA-NPs have the equal atomic ratio. Scale bar d: 10 nm, e: 0.5 nm, and f: 10 nm.
