Visualizing Under Coordinated Surface Atoms on 3D Nanoporous Gold Catalysts.
The intricate 3D geometric shape and surface atomic structure of nanoporous gold catalysts are investigated using aberration corrected scanning transmission electron microscopy in combination with discrete tomography. The real space 3D atomic configurations illustrate geometrically necessary surface defects on the curved surface of the NPG, offering atomic insights into the catalysis of the nanoporous catalyst.
