Hydroxylated Rh Single‐Atom Antennas Assembled on Carbon Nitride Toward Stable Photocatalytic Hydrogen Evolution

open access: yesAdvanced Science, EarlyView.
PCN‐Rh single‐atom catalyst shows a dual‐cycle reaction path for photocatalytic hydrogen evolution (PHE). PCN‐Rh‐0.5 achieves 32.5 times the PHE rate of PCN/Pt, which exhibits a longer operation time (192 h) with a higher amount of hydrogen production (654.5 mmol g−1) than the reported PCN‐based single‐atom catalysts and other high‐stability catalysts ...

Room‐Temperature Alane Dehydrogenation for Visible‐Light‐Driven Photocatalytic Hydrogen Supply System

open access: yesAdvanced Science, EarlyView.
In situ formed Al/MOF enables viable visible‐light‐driven photocatalytic dehydrogenation of alane (AlH3) confirming practical application. Results demonstrate that Al nanoparticles prolong lifetime of photogenerated charge carriers via localized surface plasmon resonance induced hot electron injection, while AlH3 chemisorption triggers interfacial ...

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.
