Abstract

Abstract Photocatalytic uranium extraction from seawater is an ideal strategy to obtain uranium resources. Herein, the cyano‐functionalized graphitic carbon nitride (g‐C 3 N 4 ‐CN) with an isosite structure of adsorption and photoreduction for U(VI) is successfully prepared to achieve efficient photocatalytic uranium extraction from seawater. As the key of the isosite structure, the cyano group not only dramatically promotes the separation of photogenerated charges of g‐C 3 N 4 ‐CN and enriched electrons around it, but also greatly improves the adsorption capacity and selectivity for U(VI) over g‐C 3 N 4 ‐CN by complexing with U(VI). Therefore, g‐C 3 N 4 ‐CN exhibits efficient and stable photocatalytic U(VI)…
