Photocatalytic Methanol Reforming on Au/TiO2 for Hydrogen Production
Photocatalytic Reforming Au/TiO2
<
2009/7/28
Methanol can be reformed with water, at ambient
temperature, using photocatalysis, and this reaction
represents a possible low energy, more sustainable
pathway to hydrogen production than (for inst...
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

2009/7/28
The photocatalytic activity of Au modified titanium
dioxide was evaluated in the photodegradation of
the azo dye Acid Red 1 (AR1) under 254 nm
irradiation. Noble metal nanoparticles were
deposited...
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
