Furthermore, high-angle annular dark-field scanning TEM (HAADF-STEM) analysis can clearly reveal the distribution of different elements in the catalysts with different colors. Usually, the core and shell of the catalysts can be distinguished from the dark shell and bright core, as shown in Figure 3.13. °... [Pg.102]

Three techniques have been mainly utilized to characterize gold clusters, namely mass spectroscopy, high-angle annular dark-field scanning transmission electron microscopy (HAADF-STEM), and extended X-ray absorption fine structure spectroscopy (EXAFS). For unsupported gold clusters, electrospray ionization (ESI) mass spectrometry and matrix-assisted laser desorption ionization (MALDI) mass... [Pg.405]
