Oxidation supported AuNP-catalyzed

AppUcations are expected in both the catalytic removal of CO produced at ambient temperature by engines and the removal of CO traces from dihydrogen streams feeding the fuel cells. There is a tremendous recent increase in the number of reports focusing on this area of supported AuNP-catalyzed CO oxidation, Ti02 becoming the dominant support [45]. 

Besides CO oxidation, other supported-AuNP catalyzed reactions have recently been disclosed, confirming that supported AuNPs are now a very popular means to catalyticaUy activate dihydrogen and dioxygen ... 

The field of CO oxidation, including Masatake Haruta systems, recent advances and key mechanistic issues are reviewed by Catherine Louis in Chapter 15. This chapter details the basic features of CO oxidation catalyzed by AuNPs, the preparation of the oxide supports, conditions for efficient catalysis, electronic and morpholo al properties of the catalyticaUy active supported AuNPs. It also offers deep and rational mechanistic discussions including the infiuetwe of the nature of the support. 

Metal nanoparticles (MNPs) are excellent catalysts working under mild conditions either homogeneously or heterogenized on a solid support (zeolite, charcoal, nanotubes). For instance, Haruta discovered that AuNPs on Ti02 catalyze CO oxidation by O2 to CO2 under subambient conditions, with many applications. Alkene and arenes hydrogenation under ambient conditions and cross C-C bond formation (Suzuki, Sonogashira, Heck, Stille, Corriu-Kumada) with aryl halides are catalyzed by noble metal NPs (Ru, Rh, Pd or Pt).
