Chemically stable Cr-based metal-organic frameworks: Preparation, functionalization, and applications in catalysis in liquid-phase and proton conductivity

초록

Recently, metal-organic frameworks (MOFs) have attracted much attention because of their potential applications in various fields. However, one of the drawbacks of MOFs is low stability, compared with that of inorganic porous materials like zeolites and carbonaceous materials. Cr-based MOFs, especially those composed of Cr3+ and carboxylates, are highly attractive thanks to their high chemical stability, particularly in acid conditions. In this review, the recent approaches to the synthesis of Cr-MOFs (especially via post-synthetic modifications), modification of Cr-MOFs, and application of Cr-MOFs in catalysis in the liquid phase, adsorption, and proton conduction will be discussed. Rather than analyzing the whole reported results on Cr-MOFs, some modifications and applications that are relevant to “chemically stable Cr-MOFs”, together with some special syntheses, will be discussed. In the last part, outlooks of the Cr-MOFs in the relevant fields will be provided to readers, after a summary of the chemically stable Cr-MOFs. © 2025 Elsevier B.V.
