Pt Nanoparticles Loaded on Bimetallic Porphyrinic MOF for Selective Hydrogenation Reactions

Graphical A Pt NPs incorporated MOF (Pt/PCN-224 (FeCo)) with Fe/Co single atoms has been successfully fabricated. Pt/PCN-224 (FeCo) exhibited high catalytic activity in the chemoselective hydrogenation of biomass-derived furfural (FFA) to cyclopentanone (CPO). Fe/Co sites of the ligands could effectively tune the electronic properties of Pt NPs, and Co sites could synergistically promote the hydrogen spillover, thereby enhancing the catalytic activity. 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 2 . 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.
