Influence of the partner oxide on the catalytic properties of Au/Ce x Zr 1 − x highly loaded gold catalysts

Superior Stability of Au/SiO2 Compared to Au/TiO2 Catalysts for the Selective Hydrogenation of Butadiene

“…Gold catalysts are very attractive due to their unique properties such as a high activity at low temperatures for CO oxidation and a high selectivity for a wide range of oxidation and hydrogenation reactions. − Gold is an active catalyst for selective hydrogenation of, for instance, α,β-unsaturated aldehydes, nitroaromatics, and acetylene in the presence of an excess of ethylene as well as butadiene in the presence of an excess of alkenes . Strikingly, for the selective hydrogenation of butadiene, Au is highly selective for hydrogenation of butadiene without overhydrogenation to alkanes .…”

Pd/zeolite-based catalysts for the preferential CO oxidation reaction: ion-exchange, Si/Al and structure effect

“…For instance, a set of Au/ Ce x Zr 1−x O 2 catalysts was studied by Morfin and coworkers and they found that the catalytic performance was strongly dependent on the nature of the oxide. 10 Kubacka investigated the role of the interface in Cu, Ni-CeO 2 catalysts towards hydrogen production by means of several reactions (PrOx-CO, WGS and the reforming of bio-alcohols). 11 The effect of the support was also investigated by Yamamoto in a study where bimetallic PtCu catalysts were supported on Fe 2 O 3 and CeO 2 , 12 and in this case the authors concluded that the supports have an important influence on both the structure of Pt-Cu and the reduction behaviour of the catalyst.…”
