a, b, Representative complementary BF- and HAADF-STEM micrographs showing metal nanoparticle size and spatial distribution. c, Atomic resolution HAADF-STEM micrograph of a C grain supporting Au particles. d, A C grain supporting Pd particles confirming that the Au and Pd remain separated under our reaction conditions. e, f, Representative XEDS spectra of individual Au particles and Pd particles in the catalyst, respectively. No evidence of Au or Pd migration or intermixing after the catalytic reaction was observed.
