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...
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.
