Polyoxometalate-encapsulated metal-organic frameworks for photocatalytic uranium isolation.

ABSTRACT: Recycling uranium (U) via adsorption and controlled conversion is crucial for the sustainable development of nuclear energy, in which photocatalytic reduction of U(vi) from aqueous solutions is considered one of the most effective strategies. The primary challenge in the photocatalytic elimination of U(vi) resides in the demand for photocatalysts with exceptional properties for effective U(vi) adsorption and charge separation. Herein, we developed the hybrids of polyoxometalate@Cu-metal-organic frameworks (POM@Cu-MOFs) through a self-assembly strategy and demonstrated the efficient removal of U(vi) via synergistic adsorption and photocatalysis. The abundant oxygen-rich groups in POM served as the adsorption sites, endowing POM@Cu-MOFs with a remarkable removal capacity (1987.
