Figure 7. Adsorbed CO molecules on reconstructed Au (100) surface under catalytic conditions^[74]. Aberration-corrected ETEM images in (A) vacuum and (B) a reaction environment (1.0% CO in air at 100 Pa at room temperature) taken using 80 kV. (C) The observed image in the rectangular region in (B) at higher magnification. (D) A simulated TEM image based on an energetically favorable model for CO adsorption.
