Reactivity of Au 25 clusters with Au 3 +
نویسندگان
چکیده
We report the instantaneous decomposition of the small molecular gold cluster, Au25SG18 (SG-glutathione thiolate) in the presence of externally added chloroaurate ions resulting in the instantaneous formation of the insoluble gold–glutathione polymer. The rate of decomposition, however, was much slower for the metal ions such as Ag, Fe, Cu, Ni, Cd, Zn and Sr. This chemical reactivity is shown to have no direct correlation with the electrochemical potential of the added ions. 2007 Elsevier B.V.

Investigation of structural and electronic properties of small Au n Cu m (n+m≤5) nano-clusters for Oxygen adsorption
In this study, the structures, the IR spectroscopy, and the electronic properties of AunCum (n+m≤5) bimetallic clusters were studied and compared with those of pure gold and copper clusters using the generalized gradient approximation (GGA) and exchange correlation density functional theory (DFT). The study of an O2-AunCum system is important to identify the promotion effects of each of the two...

متن کاملUnexpected reactivity of Au25(SCH2CH2Ph)18 nanoclusters with salts.
We report some interesting results of the chemical reactivity of thiolate-protected [Au(25)(SCH(2)CH(2)Ph)(18)](0) nanoclusters with two types of salts, including tetraoctylammonium halide (TOAX) and NaX. At the early stage of the reaction, [Au(25)(SCH(2)CH(2)Ph)(18)](0) was found to spontaneously convert to its anionic form ([Au(25)(SCH(2)CH(2)Ph)(18)](-)) in the presence of either type of sal...

Based on the fact the manipulation of fine nanoclusters calls for more precise modeling, the aim of this paper is to conduct an atomistic investigation for interaction analysis of particle-substrate system for pushing and positioning purposes. In the present research, 2D molecular dynamics simulations have been used to investigate such behaviors. Performing the planar simulations can provide a ...
متن کاملHydrogen adsorption on and spillover from Au- and Cu-supported Pt3 and Pd3 clusters: a density functional study.
Motivated by the use of electrodes modified at the nanoscale by supported metal species, we studied computationally how the reactivity changes in such a composite system compared to the reactivity of the individual systems, metal clusters and metal surfaces. Specifically, we examined hydrogen adsorption on and hydrogen spillover from Au- and Cu-supported Pt(3) and Pd(3) clusters, using a method...
