Hydrogen peroxide (HO) 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 HO 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 HO 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 HO production rate reaches 345 μmol h g. This study provides a new blueprint for exploring the artificial photosynthesis of HO through uranium-based metal-organic frameworks.
由于具有高效、低成本和环境友好的特性，由太阳能驱动的过氧化氢（HO）生产受到了广泛关注。寻找用于生产HO的新型光催化材料是最重要的目标之一。在这项工作中，通过溶剂热反应构建了一种新型的三维（3D）铀酰有机框架材料，并将其用于光催化生产HO。混合配体策略不仅有利于三维铀酰有机框架的构建，还将强光子吸收基团引入到框架中。框架中的噻吩和吡啶环增强了光子吸收和载流子转移。此外，在铀酰中心的氢提取反应的辅助下，HO的产率达到345 μmol h g。这项研究为通过铀基金属有机框架探索HO的人工光合作用提供了新的蓝图。
