Cerium-based metal-organic frameworks: Synthesis, properties, and applications

Abstract

Within the great variety of metal-organic frameworks (MOFs), Cerium-based MOFs (Ce-MOFs) have achieved significant interest in the recent years and different studies have reported their great potential in different applications. Ce-MOFs with diverse valence states (Ce(III) and Ce(IV)) are first classified and discussed in view of distinct topologies, inorganic building units (IBUs), connectivity, and organic linkers. Then, concisely summarized their structural properties with emphasize on exploring their structure-property relationships. Subsequently, the latest progress in the synthesis strategies of Ce-MOFs were summarized with highlighting the green strategies under ambient conditions that are applicable for scale-up production of Ce-MOFs. Moreover, their applications in different fields including; corrosion inhibitors, biomedical applications, energy storage and conversion, gas adsorption, separation, and conversion, catalysis/photocatalysis, chemical sensing, and water/wastewater treatment are highlighted. Representative examples are reviewed with a focus on elucidating the relationship between their structures, properties, and applications. Finally, the future challenges and outlooks of Ce-MOFs in practical applications are also discussed. It is hope that the present review provide inspiration for researchers in this field and be a valuable reference for extending their knowledge about MOFs.
