Catalysis by Supported Gold Nanoclusters
The physical and chemical properties of supported Au clusters are markedly sensitive to cluster size and morphology. To investigate the origin of the unique properties of nanosized Au clusters, model catalysts consisting of Au clusters of varying sizes have been prepared on single crystal TiO2(110) and ultrathin films of single crystalline TiO2, SiO2, and Al2O3. The morphology, electronic struc...
متن کاملControlling gold nanoclusters by diphospine ligands.
We report the synthesis and structure determination of a new Au22 nanocluster coordinated by six bidentate diphosphine ligands: 1,8-bis(diphenylphosphino) octane (L(8) for short). Single crystal X-ray crystallography and electrospray ionization mass spectrometry show that the cluster assembly is neutral and can be formulated as Au22(L(8))6. The Au22 core consists of two Au11 units clipped toget...
متن کاملOxygen reduction catalyzed by gold nanoclusters supported on carbon nanosheets.
Nanocomposites based on p-mercaptobenzoic acid-functionalized gold nanoclusters, Au102(p-MBA)44, and porous carbon nanosheets have been fabricated and employed as highly efficient electrocatalysts for oxygen reduction reaction (ORR). Au102(p-MBA)44 clusters were synthesized via a wet chemical approach, and loaded onto carbon nanosheets. Pyrolysis at elevated temperatures led to effective remova...
متن کاملRedox properties of self-assembled gold nanoclusters.
The redox properties of a monolayer of alkanethiolate-protected gold nanoclusters (MPCs) constructed on a gold slide electrode was studied in 1,2-dichloroethane (DCE) electrolyte solutions. The influence of the electrostatic interaction between attached MPCs and the substrate electrode on the absolute standard redox potential of MPCs was theoretically considered and studied experimentally.
متن کاملOxygen electroreduction catalyzed by gold nanoclusters: strong core size effects.
Bigger isn't better: Gold nanoclusters exhibit enhanced electrocatalytic activity in oxygen reduction when the core size decreased from Au(140) to Au(11), as reflected by the onset potential E(onset) and peak current density J(K) (see picture). The increasing fraction of surface atoms with low coordination numbers and the shift of the d-band center to the Fermi level facilitate oxygen adsorption.
