Hydrogen dissociation by gold clusters

WebIntroduction. During the last 20 years, there has been a renaissance concerning the topic of catalysis by gold [1], [2], [3]. Initially, most of this interest has been focused on the exciting discovery that supported gold catalysts, in particular Au/TiO 2 and Au/Fe 2 O 3, could oxidise CO to CO 2 at ambient temperature [4], [5], [6]. This has prompted a … Web21 dec. 2012 · The dissociation of H(2) easily occurs on the bottom layer with the energy barriers no more than 0.44 eV. The support effects on the dissociation barriers are …
