Abstract

original image

A caged catalyst: Noble-metal and oxide nanoparticles can be assembled to obtain high-temperature-stable mesoporous multicomponent nanocomposite colloidal spheres (MMNCSs; see picture). CO oxidation and cyclohexene hydroconversion were selected to examine the catalytic activity, selectivity, and thermal stability of these MMNCSs. The exhibited catalytic properties suggest that the reported MMNCSs are ideal model catalysts for high-temperature reactions.
