Abstract

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.

Graphical Abstract

Gold nanoparticles entangled in a styrene copolymer does not catalyze the oxidation of anilines to azobenzene and is somewhat less efficient for two other reactions than gold supported on nanocrystalline ceria.
