“…In the same work, oxygen labeled water H 2 18 O was used in the reaction alongside C 16 O and 16 O 2 . DRIFTS measurements then found that the CO 2 produced is a mix of C 16 O 2 and C 18 O 16 O, demonstrating that the OH − produced after proton transfer from water to adsorbed O 2 can also take part in the oxidation of CO. Fu et al have used DFT calculations to look at Au on a hexagonal BN support 251 and found that there is electron transfer between the BN surface and the Au 9 cluster they employed. This leads to a weakening of the Au−CO bond compared to an isolated cluster, which, they suggest, explains the experimentally observed blue-shift for CO adsorbed to Au/BN reported by Lin and co-workers.…”

In this review, we discuss selected examples from recent literature on the role of the support on directing the nanostructures of Au-based monometallic and bimetallic nanoparticles. The role of support is then discussed in relation to the catalytic properties of Au-based monometallic and bimetallic nanoparticles using different gas phase and liquid phase reactions. The reactions discussed include CO oxidation, aerobic oxidation of monohydric and polyhydric alcohols, selective hydrogenation of alkynes, hydrogenation of nitroaromatics, CO2 hydrogenation, C–C coupling, and methane oxidation. Only studies where the role of support has been explicitly studied in detail have been selected for discussion. However, the role of support is also examined using examples of reactions involving unsupported metal nanoparticles (i.e., colloidal nanoparticles). It is clear that the support functionality can play a crucial role in tuning the catalytic activity that is observed and that advanced theory and characterization add greatly to our understanding of these fascinating catalysts.
