Defect Engineering Activates Pyrene‐Based Covalent Organic Frameworks for Efficient Photocatalytic Uranium Capture

open access: yesAdvanced Science, EarlyView.
A defect‐engineered pyrene‐based covalent organic framework (TP‐PYTO‐SA) is developed via strategic salicylaldehyde incorporation. This approach simultaneously enhances hydrophilicity and introduces uranyl coordination sites, while optimized defect density significantly improves charge separation.

Fe/N‐Doped Carbon with Nearly Ordered Mesopores and Tunable Particle Sizes as Model Catalysts for Quantitative Evaluation of Electrocatalytic Active Sites

open access: yesAdvanced Science, EarlyView.
This study is dedicated to the design and synthesis of MOF‐derived mesoporous Fe/N‐doped carbons as model catalysts, aiming to quantitatively evaluate the utilization of active sites in the ORR. Through modulation followed by pyrolysis, we successfully prepare size‐tunable Fe/MNC‐x with doped iron atoms and mesoporous structures. The smaller Fe/MNC‐250

Light‐Promoted Hydrazine Dehydrogenation over Ni/NH2‐MIL‐125: Unraveling Mechanisms for Efficient Hydrogen Production

open access: yesAdvanced Science, EarlyView.
Highly dispersed and electron‐rich Ni nanoparticles (≈2.7 nm) supported on NH2‐MIL‐125 significantly promote the dehydrogenation of hydrous hydrazine under visible‐light irradiation, achieving a turnover frequency of 220.2 h−1 at 323 K, which is more than twice that in the dark (108.1 h−1) and outperforms most reported non‐precious metal catalysts ...
