Abstract
Hydrogen peroxide (H(2)O(2)) production driven by solar energy has received enormous attention due to its high efficiency, low cost, and environmental friendliness characteristics. Searching for new photocatalytic materials for H(2)O(2) production is one of the most important targets. In this work, a new three-dimensional (3D) uranyl-organic framework material was constructed with mixed ligands via a solvothermal reaction and used for photocatalytic H(2)O(2) production. The mixed ligand strategy not only benefits the construction of a 3D uranyl-organic framework but also introduces strong photon absorption groups into the framework. The thiophene and pyridine rings in the framework enhance photon absorption and carrier transfer. In addition, with the assistance of the hydrogen abstraction reaction of uranyl centers, the H(2)O(2) production rate reaches 345 μmol h(-1) g(-1). This study provides a new blueprint for exploring the artificial photosynthesis of H(2)O(2) through uranium-based metal-organic frameworks.
