The characterization analysis of the 3D ordered mesoporous AuAg networks. a, b The typical SEM and TEM images of the 3D ordered mesoporous AuAg networked structures synthesized via the proposed soft-enveloped SLS interface reaction. c The [1–10] zone axis nanobeam electron diffraction pattern, displaying typical {200} and {111} Bragg reflections of fcc, Au, or Ag. d–g Representative HAADF-STEM image in combination with EDX element maps. Inset in d is the fast Fourier transformation (FFT) patterns of the STEM images. h The composition line profiles obtained by EDX with an electron beam (~1.5 Å in spot size) scanning across the region marked in g. The scale bars in a and d are 100 and 2 nm, respectively
