Special Issue Information

Dear Colleagues,

Metal-organic frameworks (MOFs) are among the most promising novel materials, which was first introduced in 1990. They are a new class of crystalline porous hybrid materials with high porosity, large specific surface area and adjustable channel structure and biocompatibility. MOFs are formed by the assembly of two components: Cluster or metal ion nodes and organic linkers between them, usually giving rise to crystalline structures with an open framework and significant porous texture development. Recently, they have been investigated with increasing interest for energy storage and conversion, gas adsorption/separation, membranes, catalysis, sensing and biomedicine.

Here, we are greatly honored to assemble a special issue of the latest research work on MOFs toward their synthesis, characterization and application. Some of the key topics relevant to this Special Issue are:

  • Synthesis and characterization of novel MOFs or MOF-based materials;
  • SPE application;
  • Porous MOFs for adsorption and gas storage/capture;
  • Drug delivery application with MOF based-materials;
  • Catalysis and photocatalysis with MOFs and MOF-based materials;
  • Synthesis of MOFs for chemical sensing;
  • Energy storage in MOFs;
  • CO2 capture with MOFs and MOF-based materials.

We hope that this special issue will provide the readers some representative and exciting views regarding the new development and utilization of MOFs and MOF-related materials.

A promising solution for efficient methane (CH4) storage and transport is a metal–organic framework (MOF)-based sorbent. Hence, searching for potential MOFs like M2(BDC)2(DABCO) to enhance the CH4 storage capacity in both gravimetric and volumetric uptakes is essential. Herein, we systematically elucidate the adsorption of CH4 in M2(BDC)2(DABCO) or M(DABCO) (M = Mg, Mn, Fe, Co, Ni, Cu, Zn) MOFs using multiscale simulations that combined grand canonical Monte Carlo simulation with van der Waals density functional (vdW-DF) calculation. We find that, in the M(DABCO) series, Mg(DABCO) has the highest total CH4 adsorption capacities, with mtot= 231.39 mg/g at 298 K, for gravimetric uptake, and Vtot= 231.43 cc(STP)/cc, for volumetric uptake. The effects of temperature, pressure, and metal substitution on enhancing CH4 storage are evaluated, and we predict that the volumetric CH4 storage capacity on M(DABCO) could meet the DOE target at temperatures of ca. 238 K–268 K and pressures of 35–100 bar. The interactions between CH4 and M(DABCO) are dominated by the vdW interactions, as shown by the vdW-DF calculations. The Mg, Mn, Fe, Co, and Ni substitutions in M(DABCO) result in a stronger interaction and thus, a higher CH4 storage capacity, at higher pressures for Mg, Mn, Ni, and Co and at lower pressures for Fe. This work may provide guidance for the rational design of CH4 storage in M2(BDC)2(DABCO) MOFs. Full article

Tetrabromobisphenol A (TBBPA) is a kind of widely used brominated flame retardant (BFR), which is proven to be harmful to ecological systems and public health. It is very important to remove TBBPA from the environment. In our study, a magnetic composite named Fe3O4/GO/ZIF-67 was synthesized by a coprecipitation method and applied in the highly efficient adsorption of TBBPA from water. Static adsorption experiments demonstrated that the adsorption capacity could reach 232 mg·g−1 within 120 min, which is much higher than those reported in the other literature. The experimental results show that the adsorption of TBBPA on Fe3O4/GO/ZIF-67 followed Langmuir and pseudo-second-order kinetic adsorption models. The main mechanisms for these adsorptions were identified as hydrogen bonds between OH groups in TBBPA and COOHs of Fe3O4/GO/ZIF-67, and π-π stacking between Fe3O4/GO/ZIF-67 and TBBPA. This study provides a method with great promise for the design and synthesis of better adsorbents for the removal of TBBPA from the water environment. Full article
