Catalysis of olefin hydrogenation and allylic isomerization by immobilized gold nanoclusters

Smirnov, V. V. / Nikolaev, S. A. / Tyurina, L. A. / Vasil’kov, A. Yu.

Abstract Gold nanoparticles immobilized on carbon and oxide supports showed catalytic activity in the hydrogenation and allylic isomerization of alkenes and arylalk-1-enes. The catalysts were active only in the case when the average size of metal particles did not exceed 30 nm. Hydrogenation was accompanied by the allylic isomerization of the substrate. Under chosen conditions, the ratio of hydrogenation to isomerization rate was close to 1: 2. The activity of gold nanoparticles immobilized on oxide catalysts increases with an increase in their acidity.
