Anodic Oxidation of Ethylene and Acetylene.
Complete Oxidation of Benzene over Au-V2O5/TiO2 and Au-V2O5/ZrO2 Catalysts
Complete Oxidation Benzene Au-V2O5/TiO2
2009/7/29
A gold promotional effect is reported for the complete oxidation of benzene using Au/V2O5 supported on titania or zirconia catalysts.
A pre-requisite for good catalytic activity with supported gold is that the metal is present as nanoparticles, but no suitable method for depositing gold on carbon as nanoparticles has previously been...
Of the many important reactions that are known to be catalysed by gold particles supported on transition metaloxides, the oxidation of carbon monoxide is of outstanding significance: the current state...
The Role of Nanosized Gold Particles in Adsorption and Oxidation of Carbon Monoxide over Au/Fe2O3 Catalyst
Adsorption Oxidation Au/Fe2O3
2009/7/29
The presence of gold is found to promote the development of weakly bonded (CO)ad species over the surface ofAu/Fe2O3 catalyst during interaction with carbon monoxide (CO) or a mixture of carbon monox...
A Study on the Effect of Potentiostatically Grown Gold Oxide Films on the Oxidation of Phenol in Base
Gold Oxide Films Oxidation
2009/7/29
The general behaviour of potentiostatically grown gold oxide films during the oxidation of phenol in basicsolutions has been studied using cyclic voltammetry. No catalytic activity is observed and phe...
On the Mechanism of Selective CO Oxidation on Nanosized Au/g-Al2O3 Catalysts
Inverse Gas Chromatography Rate Constants Au catalysts
2009/7/28
New findings give further information on the
mechanism of carbon monoxide selective oxidation
over g-alumina supported nanoparticle sized gold
catalysts. a) CO2 formation, increasing with rising
t...
Application of Heterogeneous Gold Catalysis with Increased Durability: Oxidation of CO and Hydrocarbons at Low Temperature
Oxidation of CO Hydrocarbons
2009/7/28
2% Au/Al2O3 catalysts were prepared by a novel
method involving Direct Anionic Exchange (DAE). The
method produces strong bonding of the gold complex
(HAuCl4) to the alumina support with no loss of...
Preparation of a Monolith-Supported Au/TiO2 Catalyst Active for CO Oxidation
cordierite monolith gold on titania CO oxidation
2009/7/28
The development of a method for making an
adherent coating of Au/TiO2 on a cordierite monolith
is described. The optimum method entails first
forming a wash-coat of TiO2 by combining a colloidal
d...
A Novel Internally Heated Au/TiO2 Carbon-Carbon Composite Structured Reactor for Low- mperature CO Oxidation
Au/TiO2 Carbon-Carbon
2009/7/28
A compact, internally heated, catalytic reactor is
demonstrated for the low-temperature oxidation of
carbon monoxide. Carbon nanofibres were grown
on carbon felt and used as a support material for
...
Gold Complexes with Oxygen-containing Ligands as a Catalyst for Methane Oxidation
Gold complexes methane activation quantum chemical
2009/7/28
The reactions of methane with the gold complexes
[Au(OH)]–, [Au(OCH3)4]–, [Au(O(CO)2O)2]– and
[Au(O2CH)2]+, [AuI(acac)], [AuIII(acac)2]+ (acac
– acetylacetonato) were studied using the DFT/PBE
met...
Properties of TiO2 Support and the Performance of Au/TiO2 Catalyst for CO Oxidation Reaction
gold titanium dioxide carbon monoxide oxidation
2009/7/28
Gold catalysts were prepared on TiO2 supports of
different phase structures (i.e., anatase, rutile and
biphasic), TiO2 crystal size (i.e., 9-23 nm), surface
and textural properties (i.e., hydration...
Electrochemical Oxidation of Dissolved Carbon Monoxide on Gold Electrode in Alkaline Medium
Electrochemical Oxidation Gold Electrode
2009/7/28
The study of the oxidation of dissolved CO is not
much seen in the literature probably due to the
strong adsorption of CO on platinum metals in acidic
media. This work was thus undertaken to study ...
Catalytic Performance of Gold Catalysts in the Total Oxidation of VOCs
Catalytic Performance Gold Catalysts
2009/7/28
Catalysts for the oxidation of volatile organic
compounds (VOCs) were prepared by supporting
1% gold on cerium and zirconium oxides (CeO2,
Ce0.5Zr0.5O2, ZrO2) using a simple impregnation
method fo...

gold nanoparticles rutile TiO2(110)
2009/7/28
The catalytic activity of oxide-supported gold
nanoparticles depends crucially on their size. The
present work describes a dedicated set-up in which
particle size is determined by grazing incidence...
