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.

通过使用连续的“瓶装船”将Fe ₃ O ₄和Pd纳米颗粒封装在空心多孔有机纳米球（HPON）的一个腔中，合成了由卵黄壳磁性多孔有机纳米球（MPONs）负载的Pd纳米颗粒（Pd @ MPONs）。战略。所获得的Pd @ MPONs具有分层的微/中孔结构，高表面积（354 m ²/ g），并显示出极好的磁响应（9 emu / g）。它们在温和条件下和Heck-Mizoroki反应中对醇的氧化显示出很高的催化性能，并且具有出色的磁性可回收性，可以在不降低催化活性的情况下使用外部磁场将其从反应体系中快速去除。因此，Pd @ MPONs是易于回收的纳米催化剂，在未来的可持续工业中具有实际意义。
