The practical application of photocatalytic uranium removal is hampered by the inefficient charge separation of electron-hole pairs in photocatalytic systems, which limits the generation of reactive oxygen species needed for uranium precipitation. Here, the authors show that weakly localized electrons enhance the electronic coherence in fluorine-functionalized covalent organic frameworks strengthening charge separation and promoting directional electron transport to boost the photocatalytic uranium removal from nuclear wastewater.
