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.

Catalytic Kinetics Regulation for Enhanced Electrochemical Nitrogen Oxidation by Ru-Nanoclusters-Coupled Mn O Catalysts Decorated with Atomically Dispersed Ru Atoms.

Electrochemical N oxidation reaction (NOR), using water and N in the atmosphere, represents a sustainable approach for nitric production to replace the conventional industrial synthesis with high energy consumption and greenhouse gas emission. Meanwhile, owing to chemical inertness of N and sluggish kinetics for 10-electron transfer, emerging electrocatalysts remain largely underexplored. Herein, Ru-nanoclusters-coupled Mn O catalysts decorated with atomically dispersed Ru atoms (Ru-Mn O ) are designed and explored as an advanced electrocatalyst for ambient N oxidation, with an excellent Faraday efficiency (28.
