Natural gold particles in Eucalyptus leaves and their relevance to exploration for buried gold deposits
Eucalyptus trees may translocate Au from mineral deposits and support the use of vegetation (biogeochemical) sampling in mineral exploration, particularly where thick sediments dominate. However, biogeochemistry has not been routinely adopted partly because biotic mechanisms of Au migration are poorly understood. For example, although Au has been previously measured in plant samples, there has ...
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.
متن کاملSinglet Oxygen Generation by Laser Irradiation of Gold Nanoparticles
The formation of singlet oxygen by irradiation of gold nanoparticles in their plasmon resonance band with continuous or pulsed laser light has been investigated. Citrate-stabilized nanoparticles were found to facilitate the photogeneration of singlet oxygen, albeit with low quantum yield. The reaction caused by pulsed laser irradiation makes use of the equilibrated hot electrons that can reach ...
متن کاملHydrogen-promoted oxygen activation by free gold cluster cations.
Small gas-phase gold cluster cations are essentially inert toward molecular oxygen. Preadsorption of molecular hydrogen, however, is found to cooperatively activate the binding of O(2) to even-size Au(x)(+) (x = 2, 4, 6) clusters. Measured temperature- and reaction-time-dependent ion intensities, obtained by ion trap mass spectrometry, in conjunction with first-principles density-functional the...
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...
