“…It can be seen that SCNT presented one strong diffraction peak at 26° and the other weak peak at 43°, which were, respectively, distributed to the (002) and (100) planes of SCNT. And the XRD pattern of UiO‐66 was consistent with the literature . The diffraction peaks of UiO‐66‐SCNT and UiO‐66‐SCNT@GO nanocomposites were almost identical to raw UiO‐66, indicating that the introduction of carbon nanomaterials in the in situ crystallization process had no significant effect on the crystal structure of UiO‐66.…”

Summary One‐dimensional (1D) sodium ligninsulfonate functionalized carbon nanotubes (SCNT), two‐dimensional (2D) graphene oxide (GO), and three‐dimensional (3D) zirconium‐based metal‐organic frameworks (UiO‐66) are self‐assembled as filler materials for proton‐exchange membranes (PEMs) because of their potential for extending proton transport pathways. Herein, UiO‐66‐SCNT and UiO‐66‐SCNT@GO were prepared by a facile solvothermal synthesis and then the nanohybrid chitosan (CS) PEMs were fabricated via solution casting. The hybrid PEMs with higher ion exchange capacity than the pure CS membrane displayed higher proton conductivity and selectivity. The proton conductivity of nanohybrid membrane doped with 7 wt% UiO‐66‐SCNT@GO (CS/U‐S@GO‐7) was enhanced to 64 mS cm−1 at 70°C. Simultaneously, the selectivity was reached 19.4 × 104 S s cm−3 and was much higher than the pristine CS membrane (0.13 × 103 S s cm−3). Moreover, the mechanical properties of all composite membranes were significantly enhanced compared with that of the pure CS membrane. The results showed that our research provided a valuable strategy for designing high‐performance CS‐based PEMs in direct methanol fuel cell (DMFC). Highlights A simple and facile solvothermal synthesis was used to prepare UiO‐66‐SCNT@GO. UiO‐66‐SCNT@GO was introduced into chitosan (CS) matrix to optimize proton transport channels. CS‐based hybrid membranes exhibit high proton conductivity and selectivity. CS‐based hybrid membranes show low methanol permeability.

“…Although MOFs commonly exhibit much weaker stability in comparison with conventional porous materials such as activated carbon and metal oxide [130][131][132][133], UiO family is an important branch of MOFs that has a high thermal and chemical stability in comparison with other MOFs [134]. Zirconium MOFs (Zr-MOFs) are one archetypical UiO-family that is based on 12-connected metal nodes and usually adopts face-centered cubic (fcu) network topology [135].…”

Water-based routes for synthesis of metal-organic frameworks: A review

et al. 2020

View full text Add to dashboard Cite

Although metal-organic frameworks (MOFs) show numerous advantages over other crystalline materials, their industrial relevances have been impeded owing to their many drawbacks such as environmental impacts and economic costs of their synthesis. A green preparation pathway could greatly reduce the environmental costs, energy, and the need for toxic organic solvents, and consequently reduce the production cost. Thus, the most desirable synthesis route is the replacement of harsh organic solvents with aqueous solutions to abate environmental and economic impacts. This review summarizes recent research advancements of water-based routes for MOF synthesis and gives a brief outline of the most prominent examples. The challenges and prospects of the commercialization of promising MOFs in the future are also presented. This study aims to offer necessary information regarding the green, sustainable, and industrially acceptable fabrication of MOFs for their commercial applications in the future.

Diclofenac is an acidic pharmaceutically active compound and one of the most frequently detected ones in wastewater. This review discusses the research progress and innovations made in recent years on the mitigation of diclofenac from aqueous media by adsorption. It was observed that activated carbon by intense physical activation, metal organic frameworks, and chitosan‐cellulose polymeric adsorbents were the best adsorbents for diclofenac removal. Diclofenac sorption follows mainly pseudo‐second order kinetics and was best fit to either Freundlich or Langmuir isotherms. Recent research trends involved the investigation of column and continuous experiments, competitive adsorption, and adsorption with photo‐catalytic degradation. Whilst numerous types of adsorbents have been explored, there is still need for mechanistic studies.
