Abstract

Yolk-shell magnetic porous organic nanospheres (MPONs) supported Pd nanoparticles (Pd@MPONs) were synthesized by encapsulating Fe₃O₄ and Pd nanoparticles in one cavity of hollow porous organic nanospheres (HPONs) using a continuous “ship-in-bottle” strategy. The obtained Pd@MPONs possessed a hierarchically micro/mesoporous structure, high surface area (354 m²/g) and displayed excellent magnetic response (9 emu/g). They showed high catalytic performance in the oxidation of alcohols under mild conditions and the Heck-Mizoroki reaction, and brilliant magnetic recyclability, they can be removed rapidly from a reaction system using external magnetic fields without any catalytic activity decrease. Hence, the Pd@MPONs are easily recoverable nanocatalysts which have practical significance in the future sustainable industry.
