Gold atoms, reaction

In addition to the above reactions, some of the pyrolysis intermediates and products can also act as reductants (Reaction 6.5) during sonication. Such reducing species subsequently react with Au3+ to form gold atoms (Reaction 6.6), which can agglomerate to produce gold seed particles. 

The above stm study also discovered a facile transport of surface gold atoms in the presence of the Hquid phase, suggesting that the two-step mechanism does not provide a complete picture of the surface reactions, and that adsorption/desorption processes may have an important role in the formation of the final equiHbrium stmcture of the monolayer. Support for the importance of a desorption process comes from atomic absorption studies showing the existence of gold in the alkanethiol solution. The stm studies suggest that this gold comes from terraces, where single-a tomic deep pits are formed (281—283). 

Further reactions of gold atoms (132) with mixed OJCO matrices led to some interesting results. By cocondensing Au atoms with equimolar mixtures of Oj/CO at 10- 12K, a single compound was isolated which, by means of = C 0/> 02, and C 0/ = C 0/ HD /...
