In this study, a core–shell heterostructure of cuprous sulfide (Cu2S) nanoplates and covalent organic polymers (COPs) (Cu2S@COP) was constructed in situ by Cu2S-catalyzed azide–alkyne reaction for efficient reduction rapid removal U(VI) from uranium mine wastewater. The simple synthesis heterojunctions through click chemistry reactions can create tight bond at the interface evade laborious process conventional composites. different Fermi energy levels Cu2S COP induce formation built-in electric field within heterojunction, photogenerated charge transfer to nanoplate results substantial boost efficiency photocatalytic U(VI). Cu2S@COP heterojunction demonstrates high capacity 1164.6 mg g–1 without need sacrificial agent, which is 2.08 times higher than nanoplates, 3.02 COP, better most other previous heterostructures. present method involves good specificity achieves 85.9% preparation via provides new design concept composite construction presents novel strategy modulate activity contaminant management.
