From: Catalytic activities of noble metal atoms on WO3 (001): nitric oxide adsorption
Optimized atomic structure. (a) Top view and (b) side view of the clean WO3 (001) surface. The large and small circles represent W and O atoms, respectively. The most stable structures for the Cu, Ag, and Au atoms deposited on WO3 (001) surface are displayed in (c), (d), and (e), respectively. The most stable structures for NO adsorption on a clean WO3 (001) surface and the Cu-, Ag-, and Au-deposited WO3 (001) surfaces are displayed in (f), (g), (h), and (i), respectively. In (f), (g), (h), and (i), the circle for N atom is larger than that for the O atom.
