Nitrogen‐Site Isomerism Unlocks Exciton Dissociation in Vinylene‐Linked COF‐Based Photocatalysts
EcoEnergy, EarlyView.Two regioisomeric vinylene‐linked covalent organic frameworks (COFs) constructed from diazine units with different nitrogen positions are developed for photocatalytic hydrogen evolution reaction (HER). Although structurally similar, the isomeric COFs exhibit distinct electron distribution and charge‐separation behaviors, leading to a more than twofold ...

Enhanced Urea Oxidation Reaction by Mn‐Doped Nickel Hydroxide From Wastewater
ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.Mn incorporation modifies the hydroxide structure and modulates the electronic properties of the Ni centers, promoting the formation of catalytically active NiOOH species. Mn dopants induce a favorable electronic effect but do not directly participate in the UOR mechanism, enhancing the overall urea oxidation rate and resulting in increased hydrogen ...
