Chang, C. M., Cheng C., & Wei C. M. (2008).  CO oxidation on unsupported Au(55), Ag(55), and Au(25)Ag(30) nanoclusters. Journal of Chemical Physics. 128, 4., Mar, Number 12 AbstractWebsite

Using density functional calculations, we demonstrate a catalytic reaction path with activation barriers of less than 0.5 eV for CO oxidation on the neutral and unsupported icosahedral nanoclusters of Au(55), Ag(55), and Au(25)Ag(30). Both CO and O(2) adsorb more strongly on these clusters than on the corresponding bulk surfaces. The reaction path consists of an intermediate involving OOCO complex through which the coadsorption energy of CO and O(2) on these clusters is expected to play an important role in the reaction. Based on the studies for the Au and Ag nanoclusters, a model alloy nanocluster of Au(25)Ag(30) was designed to provide a larger coadsorption energy for CO and O2 and was anticipated to be a better catalyst for CO oxidation from energetic analysis.

We have observed simple oscillations in three-dimensional (3D) patterns of electron thermal diffuse scattering (separated from electron-electron energy loss) measured on a Si(001) surface. We interpret these oscillations as coherent interference within a small cluster of atoms in which vibrational correlation within the nearest neighbors (NN) is dominant. A 3D Patterson function analysis of the oscillation reveals the atomic structure of the Si(001) surface consisting of NN pairs including dimers. This finding provides a promising new clue to determine the structures of bulk and the surface of solids.
