Abstract:
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 H2. 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.

02:17Reduction of Alkenes: Asymmetric Catalytic Hydrogenation
The metal catalyst used can be either heterogeneous or homogeneous. When hydrogenation of an alkene generates a chiral center, a pair of enantiomeric products is expected to form. However, an enantiomeric excess of one of the products can be facilitated using an enantioselective reaction or an...

Metals like palladium, platinum, and nickel are commonly used in their solid forms — fine powder on an inert surface. As these catalysts remain insoluble in the reaction mixture, they are referred to as heterogeneous catalysts.
