Dimethylgold acetylacetonate

Chemical vapor deposition (CVD) has been used to prepare nanoparticle catalysts, although the technology is quite expensive. Dimethylgold acetylacetonate absorbs on supports such as MgO. Decomposition at > 100°C produces an efficient CO oxidation catalyst. X-ray absorption near edge (XANES) and extended X-ray absorption fine structure spectroscopies (EXAFS) showed that, under steady-state CO oxidation conditions, the catalyst contained Au(0) in the form of (on average) Aus clusters and also additional gold as... 

A stream of volatile compound of gold is transported onto a high area support by an inert gas and it reacts chemically with the surface of the support. Dimethylgold acetylacetonate has been used in this way to prepare gold on alumina, titania, silica, MCM-41, and carbon.
