Research on Gold In Catalysis.
As for many aspects of gold science and technology, gold catalysis has unique features. Until recently, gold catalysis has had an uncertain history, but research work in a number of laboratories has n...
Some of the unique features of gold catalysis were described in Part 1. Further examples of reactions catalysed by supported transition metal oxides are given in this second part. These include both s...
Gold has long been regarded as an “inert” surface and
bulk gold surfaces do not chemisorb many molecules
easily. However, in the last decade, largely through the
efforts of Masatake Haruta, gold pa...
Application of Heterogeneous Gold Catalysis with Increased Durability: Oxidation of CO and Hydrocarbons at Low Temperature
Oxidation of CO Hydrocarbons

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...
