Uranium (U), a high-performing, low-emission energy source, is driving sustainable economic growth. Herein, we synthesized two crystalline phases (HPOC-α and β) by an unreported amidoxime organic cage used for uranium capture. The revealed crystal structures adsorption test showed that accessible functional groups were essential to uranyl ions sorption. presented in HPOC-α gifted it equilibrium capacity of 1682 mg g–1 could mostly maintain the performance after adsorption–desorption cycles. In natural seawater, exhibited impressive recovery 11.97 during 30 day field testing, showing potential economically practical extraction from seawater.

Abstract In this study, graphene oxide (GO) and polyacrylamide/polyacrylic acid (PAM/PAA) are used to prepare hydrogels with photothermal conversion properties for highly efficient uranium extraction from seawater. Zwitterionic 2‐methacryloyloxy ethyl phosphorylcholine (MPC) is introduced in the PAM/PAA/GO hydrogel obtain PAM/PAA/GO/MPC (PAGM), exhibiting good antibacterial properties. PAGM demonstrates specific adsorption of (VI) (U(VI)). Under light conditions, capacity reaches 196.12 mg g −1 (pH = 8, t 600 min, C 0 99.8 L , m/v 0.5 ).

Abstract Photocatalytic uranium extraction from seawater is an ideal strategy to obtain resources. Herein, the cyano‐functionalized graphitic carbon nitride (g‐C 3 N 4 ‐CN) with isosite structure of adsorption and photoreduction for U(VI) successfully prepared achieve efficient photocatalytic seawater. As key structure, cyano group not only dramatically promotes separation photogenerated charges g‐C ‐CN enriched electrons around it, but also greatly improves capacity selectivity over by complexing U(VI). Therefore, exhibits stable reduction performance, a saturated 2644.3 mg g −1 , significantly higher than most reported ‐based photocatalysts. Moreover, it performs well in solar light‐driven actual Briefly, this work illustrates importance constructing improving performance.

Abstract Environmental protection and resource reclamation make the extraction of uranium from uranium‐containing wastewater be a key role in nuclear chemistry industry. Although previous studies have revealed several effective methods materials for such use, however, few are concerned about discharge issues. In fact, direct treated into environment is still not green way. Here, an innovative conversion approach shown, which can simultaneously achieve to valuable chemical. This concept implemented by azobenzene‐pendent covalent organic framework, showing smart trans ‐to‐ cis photoresponsive properties both space electronic structure consequently, largely enhanced efficiency under UV irradiation, relative visible light irradiation. real wastewater, material found give selective 100% H 2 O generation (1872.3 µmol g −1 h ).
