Cerium (IV)-based metal-organic frameworks (MOFs) are highly desirable due to their unique potential in fields such as redox catalysis and photocatalysis. However, due to the high reduction potential of CeIV species in solution, it is still a great challenge to synthesize CeIV-MOFs with novel structures, which are extremely dominated by the hexanuclear Ce−O cluster inorganic building units (IBUs). Herein, a Ce−O IBU chain containing CeIV-MOF, CSUST-3 (CSUST: Changsha University of Science and Technology), was successfully prepared using the k...
