Abstract

Porous Pd@m-C/SiO₂ nanopeapods are prepared by a nanoconfinement method. The Pd nanoparticles show high efficiency and stability in chemical reactions such as reduction of nitrobenzene by H₂ and reduction of NO by NH₃. The high catalytic activity is attributed to the unique peapod structure, mesoporous wall, and large specific surface area on Pd@m-C/SiO₂ rendering the Pd nanoparticles highly active in chemical reactions.
