Gold Catalysts for Olefin Hydrogenation.
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...
Nitric Oxide Reduction with Hydrogen, Carbon Monoxide, and Hydrocarbons over Gold Catalysts
Nitric Oxide Hydrogen
2009/7/29
The reactivity of nitric oxide with reducing gases, using supported gold catalysts is reviewed and assessed in comparison with the use of other precious metal catalysts. Applications for this technolo...
This review summarizes the results reported in the
literature on the water gas shift (WGS) over goldcontaining
catalysts. Attention is focused on the
influence of the preparation method and the nat...
The use of the combination of homogeneous
gold-catalysts and alkynes in organic synthesis is
reviewed from its beginnings in C-N-bond formation to
the newest developments in C-C-bond formation.

New Gold and Silver-Gold Catalysts in the Shape of Sponges and Sieves
Catalysis surface chemistry gold silver nanoparticle
2009/7/28
Gold with a nanoporous sponge-like morphology,
generated by leaching of AuAg alloys is presented as
a new unsupported material system for catalytic
applications. The role of residual silver for cat...
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...
Supported gold catalysts for selective hydrogenation of 1,3-butadiene in the presence of an excess of alkenes
gold ceria titania alumina zirconia reducibility
2009/7/28
Supported gold catalysts were investigated in the
selective gas phase hydrogenation of 1,3-butadiene in
an excess of propene (0.3% butadiene, 30% propene
and 20% hydrogen), in order to simulate the...
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)
