Published: Jan. 23, 2024

Nuclear power provides a chance for the decarbonization of global energy-related emissions. However, spent fuel produced by nuclear reactors contains various radionuclides, which require further disposal and treatment. Therefore, enrichment separation radionuclides are great significance recycling utilization resources. Organic polymer materials have attracted attention due to their excellent physicochemical properties rapid kinetics, high adsorption capacity, selectivity, diverse functionalization. This review an overview use pristine polymers, functionalized polymer-based composites highly efficient different kinds (i.e., U, Tc, I). The synthesis strategy, ability, related mechanism comprehensively summarized. structure–property relationships in that underpin outstanding environmental remediation performance also illustrated. Finally, challenges perspectives future radionuclide legacy waste management reasonably proposed, aiming design functional polymers task-specific applications.

All‐in‐One: Photo‐Responsive Lanthanide‐Organic Framework for Simultaneous Sensing, Adsorption, and Photocatalytic Reduction of Uranium

Advanced Functional Materials, Journal Year: 2024, Volume and Issue: unknown

Published: May 7, 2024

Abstract The selective removal and immobilization of uranyl ions from aqueous solutions is essential for the sustainable development nuclear energy. Herein, a robust lanthanide‐organic framework material ( IHEP‐24 ) developed simultaneous fluorescence sensing, adsorption, photocatalytic reduction uranium, integrating three different functions in one material. confined space formed by coordination assembly viologen derivative ligands metal‐oxygen clusters can act as precise recognition sites uranyl, allowing to efficiently detect capture ions. In addition, presence viologen‐based radical ligand enables further adsorbed amorphous UO 2 . mechanisms adsorption photocatalysis are revealed batch experiments, photoelectrochemical characterizations, theoretical calculations. This study provides reference construction multi‐functional MOF materials also support deep radionuclides solution.
