Two-dimensional stable and ultrathin cluster-based metal–organic layers for efficient electrocatalytic water oxidation

The report describes the successful synthesis of CoNi bimetal two-dimensional CMOLs directly grown on Ni foam (Co_0.6Ni_0.4-CMOLs/NF), which shows excellent catalytic activity and stability for the OER under alkaline conditions.

Metal-Organic Framework-Based Catalysts with Single Metal Sites

Metal-organic frameworks (MOFs) are a class of distinctive porous crystalline materials constructed by metal ions/clusters and organic linkers. Owing to their structural diversity, functional adjustability, and high surface area, different types of MOF-based single metal sites are well exploited, including coordinately unsaturated metal sites from metal nodes and metallolinkers, as well as active metal species immobilized to MOFs. Furthermore, controllable thermal transformation of MOFs can upgrade them to nanomaterials functionalized with active single-atom catalysts (SACs). These unique features of MOFs and their derivatives enable them to serve as a highly versatile platform for catalysis, which has actually been becoming a rapidly developing interdisciplinary research area. In this review, we overview the recent developments of catalysis at single metal sites in MOF-based materials with emphasis on their structures and applications for thermocatalysis, electrocatalysis, and photocatalysis. We also compare the results and summarize the major insights gained from the works in this review, providing the challenges and prospects in this emerging field.

Tuning the flexibility of interpenetrated frameworks by a small difference in the fluorene moiety

[Zn₂(FDC)₂(bpy)] (LMOF-202) and [Zn₂(OFDC)₂(bpy)] (LMOF-201) (FDC: fluorene-2,7-dicarboxylate, OFDC: 9-fluorenone-2,7-dicarboxylate, bpy: 4,4'-bipyridine) have interpenetrated isostructures. However, their gas sorption behaviors indicate that LMOF-202 is rigid, whereas LMOF-201 is flexible. We found that the structural flexibility of LMOF-201 was due to the addition of only one oxygen atom into the ligand.

A hydrostable anionic zinc-organic framework carrier with a bcu topology for drug delivery

A hydrostable anionic zinc-organic open framework with a bcu topology was synthesized based on 2,5-furandicarboxylate ligand by a solvothermal process and exhibited a 17.2 wt% 5-fluorouracil payload, constituting a negligible cytotoxicity effect.
