The construction of a stable hydrogen-bonded organic framework for the photocatalytic reduction and removal of uranium

Abstract

An imidazolyl hydrogen-bonded organic framework (HOF-T) with outstanding thermal and water stability was constructed by C–H⋯N hydrogen bonding and C–H⋯π interactions. UO₂²⁺ can be selectively captured by the imidazole group of HOF-T and rapidly reduced to UO₂ under visible light irradiation, realizing exceptional uranium removal with high capacity and fast kinetics.
