Comparison of the Catalytic Activity of Gold Nanoparticles Supported in Ceria and Incarcerated in Styrene Copolymer

The catalytic activity of gold nanoparticles supported on nanoparticulated ceria or incarcerated in a styrene copolymer has been compared for three general gold catalyzed reactions, namely the aerobic benzylamine and aniline oxidations and for phenylacetylene-amine-benzaldehyde coupling. Remarkable differences between the activity of both catalysts were observed.
