| Research Abstract |
Core-hollow shell nanocomposites are expected as the facile structure of heterogeneous catalyst because they can stably immobilized metal nanoparticles inside the shell. In this work, preparations of core-hollow shell structure encapsulating palladium or nickel nanoparticles and effect of the core-hollow shell structure on the catalytic properties were investigated. As a result, core-hollow shell structure provided high thermal stability of metal nanoparticles toward coalescence and/ or aggregation due to the physical isolation of each metal nanoparticle from neighboring nanoparticles. Core-hollow shell nanocomposites with smaller pore volume showed lower catalytic activity because of the inhibition of mass transfer.
