Shape-Controlled Surface-Coating to Pd@Mesoporous Silica Core-Shell Nanocatalysts with High Catalytic Activity and Stability.

Cubic Pd nanocrystals with shape-controlled mesoporous silica shells have been theoretically designed and successfully synthesized for investigating the effect of a porous nanoshell on catalytic performance of the core. Cubic Pd@cubic mesoporous silica keeps activity of all facets and shows highest catalytic activity and enhanced reusability in the hydrogenation of nitrobenzene.
