Electrocatalytic Urea Production with Nitrate and CO₂ on a Ru‐Dispersed Co Catalyst

Advanced Functional Materials, Journal Year: 2024, Volume and Issue: unknown

Published: Aug. 12, 2024

Abstract Urea electrosynthesis from co‐electrolysis of NO 3 − and CO 2 (UENC) provides an alternative route for realizing efficient sustainable urea production. In this work, single‐atom Ru dispersed on Co (Ru 1 Co) is demonstrated as effective robust catalyst the UENC. situ spectroscopic measurements theoretical simulations unravel cooperative effect sites to promote UENC process via a tandem catalysis mechanism, where site activates adsorption hydrogenation form * NH , while hydrogenation/deoxygenation CO. The generated then transferred nearby which promotes C─N coupling toward formation. Strikingly, assembled in flow cell shows highest urea‐Faradaic efficiency 50.1% with corresponding yield rate 22.34 mmol h −1 g at −0.5 V (RHE), superior most reported catalysts

Regulating interaction with surface ligands on Au25 nanoclusters by multivariate metal–organic framework hosts for boosting catalysis

National Science Review, Journal Year: 2024, Volume and Issue: 11(10)

Published: July 23, 2024

ABSTRACT While atomically precise metal nanoclusters (NCs) with unique structures and reactivity are very promising in catalysis, the spatial resistance caused by surface ligands structural instability poses significant challenges. In this work, Au25(Cys)18 NCs encapsulated multivariate metal–organic frameworks (MOFs) to afford Au25@M-MOF-74 (M = Zn, Ni, Co, Mg). By MOF confinement, Au25 showcase highly enhanced activity stability intramolecular cascade reaction of 2-nitrobenzonitrile. Notably, interaction between nodes M-MOF-74 is able suppress free vibration on thereby improve accessibility Au sites; meanwhile, stronger interactions lead higher electron density core expansion within Au25(Cys)18. As a result, exhibits trend Au25@Ni-MOF-74 > Au25@Co-MOF-74 Au25@Zn-MOF-74 Au25@Mg-MOF-74, highlighting crucial roles microenvironment modulation around hosts.
