Core-Shell Nanostructured Supported Size-Selective Catalysts with High Catalytic Activity
We report the synthesis of a highly active, supported nanostructured metal nanoparticle catalyst with an ultrathin porous shell and gaps between the metal nanoparticles and the shell for size-selective reactions. The sizeselectivity of the catalysts could be realized through the porous shell. The gaps were able to reduce catalytic activity loss due to the contact areas between the shell and the catalytic sites. Evaluations of the activity and selectivity of the catalysts were made by catalytic hydrogenation of n-hexene versus ciscyclooctene. Further verification of the high catalytic activity of the nanostructured catalysts was by oxidation of carbon monoxide.
