Abstract Covalent organic frameworks (COFs) without donor–acceptor pairs or inefficient separation of photogenerated electrons are usually considered unfavorable for photocatalysis due to electron‐hole recombination. However, the study demonstrates a nitrile (CN) functionalized covalent framework nano‐traps (COF‐nTs; COF‐nTS 1 , 2 and 3 ), in which CN groups act as electron‐withdrawing centers, surrounding electron facilitating charge separation, transport, adsorption process. To further enhance efficiency carriers, special approach is introduced integrate morphology control through acid regulation defect engineering. These key strategies optimize structure improve photocatalytic performance, achieving maximum uranium extraction capacity 3548.1 mg g −1 significantly higher than previously reported COF‐based photocatalysts under visible light. A flexible × 6 cm film COF‐nTs prepared by blade coating method, successfully extracting from spiked seawater with 7‐day 76 saturation 193 0.2 day half time. This its potential aqueous solutions.
