Visualizing Under-Coordinated Surface Atoms on 3D Nanoporous Gold Catalysts.
ADVANCED MATERIALS(2016)
摘要
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.
