Pt Nanoparticles Loaded on Bimetallic Porphyrinic MOF for Selective Hydrogenation Reactions
Metal nanoparticles (MNPs) loaded on metal-organic frameworks (MOFs) show promising catalytic performances in various reactions, but finely tuning the electronic properties of MNPs remains challenging. Herein, metal NP-MOF synergy has been finely regulated by incorporating Pt NPs into PCN-224 (FeCo). The as-prepared Pt/PCN-224 (FeCo) exhibited high catalytic activity in the hydrogenation of various carbonyl substrates. Detailed characterizations and mechanistic studies revealed that the Fe/Co sites of the ligands can effectively tune the electronic properties of Pt NPs, which achieved promoted capability to activate H<sub>2</sub>. The atomic hydrogen (H*) produced by Pt sites mainly migrated to the Co sites to promote the hydrogenation process via hydrogen spillover, thereby enhancing the catalytic activity. This work is devoted to a promising strategy to optimize the catalytic performance of MOF-based nanomaterials by incorporating metal NPs in the thermocatalytic systems.
