Supported gold catalysts for selective hydrogenation of 1,3-butadiene in the presence of an excess of alkenes

Application of Au–Cu nanowires fabricated by laser ablation in superfluid helium as catalysts for CO oxidation

“…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].…”

Hydrogenation over gold catalysts: The interaction of gold with hydrogen

“…Gold catalyzes various hydrogenation reactions such as the hydrogenation of alkenes (3)(4)(5)(6)(7)(8)(9)(10)(11)(12), alkadiens (13)(14)(15)(16)(17)(18) alkynes (13,(19)(20)(21)(22)(23)(24)(25), , -unsaturated carbonyl compounds and nitro compounds (47)(48)(49)(50)(51)(52)(53). In contrast to traditional hydrogenation catalysts such as platinum, palladium or ruthenium, which require modification, it often shows remarkable selectivities when multiple functional groups are present.…”

Theoretical insights on the effect of reactive gas on the chemical ordering of gold-based alloys

“…Bimetallic gold-palladium alloy Au-Pd catalyst is one of the bimetallic systems that have attracted the most significant interest due to its superior performance in various catalytic reactions [1,2,[5][6][7]10]. The interplay between gold and palladium components leads to its superior catalytic reactivity in terms of the so-called ligand and ensemble effects [39].…”

“…The desire to synthesise efficient catalysts with well-defined, controllable properties and structures at the nanometre scale has generated great interest in bimetallic nanoclusters [1,2]. One of the major reasons for such interest is the fact that their chemical and physical properties may be tuned by varying the composition and the size of the clusters, which leads to different atomic ordering.…”
