Abstract: Controllable integration of metal nanoparticles (NPs) and metal-organic frameworks (MOFs) is of significant importance in many applications owing to their unique properties. In situ efficient synthesis of metal NPs with different structures into MOFs is a great challenge. Herein, we report the nanostructures of octahedron and flower Pt-Cu frame@HKUST-1, which is successfully synthesized under a microwave irradiation method in only 30 min. In this study, Pt-Cu alloys, serving as the self-template, are synthesized first, followed by the HKUST-1 shell growing in situ via the consumption of Cu0. As multifunctional catalysts, the core-shell structures exhibit excellent performance for the hydrogenation of 1-hexene. Notably, octahedron Pt-Cu frame@HKUST-1 displays high turnover number (TON) and turnover frequency (TOF) of 1004 and 2008 h-1, respectively. Thanks to the protective effect of HKUST-1, the octahedron Pt-Cu frame@HKUST-1 can be recycled for at least four runs without serious loss of activity and obvious aggregation of Pt-Cu alloys. Furthermore, the size-selective catalysis is also well-demonstrated by choosing 1-hexene, cis-cyclooctene, and styrene as substrates. [ABSTRACT FROM AUTHOR]
