“…However, the original breakthrough in the catalysis by gold should be linked with Haruta (1987), who demonstrated that gold can be an excellent catalyst when supported on metal oxides in a dispersed state [4]. The recent progress in heterogeneous catalysis resulted in remarkable investigations that showed the high activity of gold nanoparticles in the conversion of alcohols to synthetic hydrocarbons [5,6], selective oxidation of propene [7,8], synthesis of hydrogen peroxide [9,10], water gas shift reaction [11,12], hydrogenation of alkenes [13,14], isomerization [15,16], and hydrodechlorination [17,18]. The desired Cu, Ce, and Au contents in the catalysts were 0.32, 0.71, and 1 wt.…”

“…The recent progress in heterogeneous catalysis by gold resulted in remarkable investigations that demonstrated the high activity of 3-10-nm gold particles in the conversion of bioethanol to synthetic hydrocarbons [2], water gas shift reaction [3,4], selective hydrogenation of alkynes [5][6][7][8], hydrodechlorination of organic molecules [9,10], and CO oxidation [11][12][13]. Numerous data on gold catalysis indicate that, apart from the critical particle size (3-5 nm) [1,14], significant roles for catalytic activity are played by particle shape [13,15], particle surface chemistry [16,17], the support nature [10,18], mutual arrangement of particles, the sign and quantity of the electric charge on the nanoparticle surface [19,20].…”

The copper-doped gold nanowires (4 nm in diameter) were produced by the novel technique based of laser ablation of Au-Cu alloy inside superfluid helium. The principle of the method is using the quantized vortices as the 1D template for the condensation of the ablation products into thin threads. The nanowires were applied as the catalyst in СО oxidation with oxygen. The activity of Au-Cu nanowires deposited on glass filters was compared with that for monometallic and bimetallic Au and Cu particles (3-8 nm in diameter) deposited on alumina by traditional deposition-precipitation and impregnation techniques. The apparent activation energies of the reaction (Еа) were 95 and 98, 150, and 147 kJ/ mol for Au-Cu nanowires and Au-Cu, Au, and Cu particles, respectively. During running-in of the Au-Cu nanowirebased catalyst, Еа decreased to 20 kJ/mol and retained at this level in the subsequent cycles of lowering and raising the reactor temperature.

“…[168][169][170] Nikolaev and co-workers examined the gas phase hydrogenation of phenylacetylene/styrene mixtures over Au/ Al 2 O 3 . [80][81][82] Selectivity to styrene was below 30% and activity was dependent on Au particle size (2.5-30 nm). 81,82 The data given in Table 11.8 demonstrate exclusive phenylacetylene conversion to styrene over Au/Al 2 O 3 at 353 K. An increase in reaction temperature (to 473 K) resulted in an order of magnitude increase in TOF with styrene as principal product and secondary formation of ethylbenzene.…”

Gold finds diverse uses that cut across the automotive, electronics, medicine, nanotechnology, space and engineering sectors. 1-3 Catalysis by gold is now a priority growth area in terms of technological applications. 4 This has resulted in a number of review articles that have considered different aspects of gold catalysis. [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] Bond and co-workers have provided an overview of the status of related research in 1999 and 2006, 5,6 focusing on physicochemical properties, synthesis, characterisation and applications, notably in CO oxidation and the water gas shift reaction. In a more recent article, Bond highlighted the reactivity of gold at the nanoscale in activating small molecules. 20 A number of reviews have examined the catalytic action of gold in selective oxidation and we can flag critical assessments by Hutchings, Edwards and co-workers (catalyst preparation and characterisation), 7 Chen and Goodman (use of Au/TiO 2 as model catalyst),
