Abstract Photo‐assisted uranium extraction from seawater (UES) is regarded as an efficient technique for resource recovery, yet it currently faces many challenges, such issues like biofouling resistance, low charge separation efficiency, slow carrier transfer, and a lack of active sites. Based on addressing the above novel oxygen‐deficient Co 3 O 4‐x /g‐C N 4 p–n heterojunction developed photo‐assisted seawater. Relying defect‐coupling synergistic effect, redistribution molecular density formed built‐in electric field revealed by DFT calculations, significantly enhancing efficiency carriers accelerating their migration rate. Notably, oxygen vacancies served capture sites oxygen, effectively promoting generation reactive species (ROS), thereby improving performance antibacterial activity. Thus, under simulated sunlight irradiation with no sacrificial reagent added, extracted high amount 1.08 mg g −1 25 L natural after 7 days, which superior to most reported carbon nitride‐based photocatalysts. This study elaborates important role surface defects inerface engineering strategies in photocatalytic performance, providing new approach development design material

When designing new conjugated microporous polymers (CMPs), major efforts are typically focused on selecting specific linkages and variations of building blocks to control their terminal structure function. However, the constitutional isomerism CMPs has seldom been considered so far as a crucial aspect. Herein, we successfully synthesize pair isomeric CMPs, named DBP-TEP (with phenanthrenequinone units) DBQ-TEP anthraquinone units). Benefiting from construction extended D-π-A skeleton, our characterized by low band gaps high charge transport efficiency, thus remarkably enhancing uranium photoreduction performance. Interestingly, experiment results show that adsorption capacity is 1.5 times under light irradiation. Additionally, both experiments in real-life theoretical calculations prove phenanthrenonequinone unit does have profound effect photocatalytic activity, which predominantly attributed stronger electronic push-pull system higher π-conjugated DBP-TEP.
