Single Atomic Uranium Catalysts and Preparation Method Thereof

The invention discloses a single atomic uranium catalyst and a preparation method thereof, belonging to the technical field of catalyst preparation. Firstly, a chelating agent is used for stabilizing uranium compounds to form uranium complex molecules; Subsequently, in the self-assembly process of MOF, uranium complex molecules will be confined to MOF channels; Finally, through high-temperature calcination in inert or reducing gas, nitrogen-doped carbon derived from MOF can immobilize uranium atoms, thus avoiding uranium agglomeration into clusters and nanoparticles. The method is easy to operate, and the obtained uranium single atom material has good thermal stability and is not easy to sinter and agglomerate. According to the invention, a nitrogen-doped carbon-supported single atomic uranium catalyst is synthesized for the first time, which provides reference for the reasonable design of actinide single atom materials.
