“…The use of Cr and Febased MOFs for the remediation of dyes, pharmaceutical and personal care products has been reported. [41][42][43] Recently, we reported on the effective removal of chrysene from aqueous solution onto Fe-based MOFs 44 with signicant improvements in adsorption capacities compared to other conventional adsorbents and other MOFs that are plagued by chemical and thermal stability, especially under harsh conditions, which limit their applications. Thus, Fe-based MOFs offer promising features in terms of water and moisture resistance coupled with exceptionally high porosity.…”

“…We speculate that this may be due to the fact that the MOF materials are in a narrow pore state at 25% pore occupancy. [ 46 ] Owing to the overlap of potential energy, the van der Waals interactions between IL and the framework of MOF can be significantly enhanced, resulting in strong host–guest interactions, and thus excellent proton conductivity. As the amount of IL increases, the pore structure of the MOF is opened and converted into a macroporous form.…”

The low‐cost, high specific surface area and porosity, controlled pore size, and chemical properties of metal–organic framework (MOF) materials have attracted much attention in the exploration of proton conduction. The method of chemically modifying MOF structures or introducing conductive medium into the holes can effectively improve the proton conductivities of the materials. Here, the structural tunability of ionic liquid (IL) and flexible MOF (fle‐MOF) materials are matched to give full play to the conductivity of IL, the framework support, and the microporous effect of MOFs, which achieves the synergistic effect of performance and expands the temperature range of proton transfer. Three kinds of CS/IL@fle‐MOF membranes were prepared by combining three fle‐MOFs with 1‐carboxymethyl‐3‐methylimidazole (CMMIM) in different proportions to obtain 15 pieces of membranes. The comparative analyses show that CS/IL@fle‐MOF membranes have excellent proton conduction performance at a wider temperature range (263–353 K) and lower relative humidity (75% RH). Among them, the proton conductivities of CS/CMMIM@MIL‐88A‐25% and CS/CMMIM@MIL‐88B‐125% are up to 1.33 and 1.42 S cm−1 at 75% RH and 353 K, respectively; whereas those of CS/CMMIM@MIL‐53(Fe)‐75% and CS/CMMIM@MIL‐88B‐125% reach up to 2.1 × 10−3 and 1.28 × 10−3 S cm−1 at 75% RH and 263 K, respectively. The Ea of CS/CMMIM@fle‐MOFs is in the range of 0.1–0.5 eV, suggesting that the proton transport follows predominantly the typical Grotthuss transfer mechanism. The results of this study indicate that the CS/CMMIM@fle‐MOF membranes combinations offer great potential for the design of composite porous proton‐conducting materials.

A novel type of ZIF‐8/α‐ZrP (zeolitic imidazolate frameworks‐8/α‐zirconium phosphate) hybrid was obtained through surface modification of α‐ZrP by ZIF‐8 and was characterized. Subsequently, ZIF‐8/α‐ZrP was added to polyurethane elastomer (PUE) by simple blending, and the thermal behavior, flame retardancy, and smoke suppression properties of the ZIF‐8/α‐ZrP hybrid on PUE were studied. Compared with pure PUE, the test results showed that the char yield of the ZIF‐8/α‐ZrP/PUE composite at 700°C and its Tg values were increased, respectively. The peak heat release rate and total heat release of the ZIF‐8/α‐ZrP/PUE composite decreased by 69.6% and 45.6%, respectively. Meanwhile, its smoke production rate and total smoke production decreased by 59.3% and 40.5%, respectively. The improved flame retardancy and smoke suppression were primarily ascribed to the physical barrier and catalytic carbonization effects of α‐ZrP. Furthermore, the metal oxide decomposed by ZIF‐8 could further facilitate the production of char residue and raise the compactness of the char layer.
