Abstract

Heterogeneous uranyl catalysts were constructed on Hf-MOLs via SBU/linker modifications. BTB-Hf-MOL-U (UO₃ nanoparticles) exhibits enhanced photocatalytic activity, while TPY-Hf-MOL-U (single-site) shows superior stability. This approach utilizing low-radioactivity depleted uranium addresses recyclability and contamination issues in homogeneous systems, enabling efficient C–H activation under blue light irradiation.
