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
...
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...
An unconventional Au/TiO2 PROX system for complete removal of CO from non-reformate hydrogen
Au/TiO2 PROX system CO non-reformate hydrogen
2009/7/28
Au-based catalysts, generally known for high activity
in the selective catalytic oxidation of CO to CO2 at
ambient temperatures, can play a significant role in
increasing the fuel cell system’s CO ...
Looking by grazing incidence small angle x-ray scattering at gold nanoparticles supported on rutile TiO2(110) during CO oxidation
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...
Synthesis of High Performance Hydroxyapatite-Gold Catalysts for CO Oxidation
CO oxidation deposition-precipitation process
2009/7/28
Catalysts for low temperature CO oxidation were
prepared by decorating hydroxyapatite (HAp) ceramic
foam scaffolds with highly dispersed gold
nanocrystals using a deposition-precipitation (DP)
pro...

Structure of gold/oxide interface its effect on CO oxidation
2009/7/28
The interfacial interaction of gold nanoparticles
deposited on either model SiO2/Si(100) or high
surface area amorphous or mesoporous silica with
minute amounts of promoter oxide like “active”
