2017

Metal-organic frameworks (MOFs) have been widely studied for different applications owing to their fascinating properties such as large surface areas, high porosities, tunable pore sizes, and acceptable thermal and chemical stabilities. Ionic liquids (ILs) have been recently incorporated into the pores of MOFs as cavity occupants to change the physicochemical properties and gas affinities of MOFs. Several recent studies have shown that IL/MOF composites show superior performances compared with pristine MOFs in various fields, such as gas storage, adsorption and membrane-based gas separation, catalysis, and ionic conductivity. In this review, we address the recent advances in syntheses of IL/MOF composites and provide a comprehensive overview of their applications. Opportunities and challenges of using IL/MOF composites in many applications are reviewed and the requirements for the utilization of these composite materials in real industrial processes are discussed to define the future directions in this field.

“…The porosity data show that IMDC possesses a smaller surface area and pore volumes than MDC. Elemental analysis and the XPS results of IMDC, shown in Table S1, indicate the presence of nitrogen IMDC has appreciable surface nitrogen (even though much less than bulk nitrogen), which is different from MDC that contains almost no surface nitrogen [65]. Moreover, the FTIR spectrum of IMDC, shown in Fig.…”

“…Based on the polar natures of DUR and 2,4-D, the surface functional groups of IMDC (such as carboxylic, lactonic, and phenolic; Table 3), along with its surface nitrogen species (pyridinic and pyrrolic) observed by XPS analysis [65], H-bonding can be considered as an effective adsorption mechanism. Both the adsorbents and adsorbates investigated in this study can act as H-bond donors or acceptors.…”

“…The resultant MDC was applied in liquid phase adsorption for the removal of pharmaceuticals and personal care products (ibuprofen and diclofenac), antibiotics (ciprofloxacin), and organic dye (methylene blue) from water [62][63][64]. Very recently, nitrogen-containing highly porous MDCs were prepared from ZIF-8 after the introduction of the ionic liquid (IL) 1-butyl-3-methylimidazolium bromide [65]. However, utilization of the material was not studied in detail even though possible application in liquid-phase adsorptions (fuel and water purification) was reported [65].…”

Therefore, more detailed studies of the application of nitrogen-containing MDCs obtained from IL@MOF, termed IMDC (ionic liquid@MOF-derived carbons), in aqueous phase adsorption are required; moreover, such materials are inherently interesting because of their high porosity and hydrophobic nature.…”

production, especially for hydroelectricity, sunlight, and wind energy, which cannot be gathered or released when they are needed. [5][6][7][8] Electrochemical energy storage devices provide a promising approach for the storage of electric energy from these sources. [9][10][11] Currently, carbonaceous materials have attracted much interest for their extensive applications including adsorption, [12] catalysis, [13] batteries, [14] fuel cells, [15,16] supercapacitors, [17,18] and drug delivery and imaging. [19] In addition, some sensors are also one of the important applications of carbonaceous materials, because they are closely related to human health. [20,21] For instance, Emran and co-workers [22] constructed ultrasensitive biosensors with N-doped mesoporous carbon (NMC)-based electrodes for in vitro monitoring of DA released from living cells. With the further study of the experiment, they also designed a series of S-doped carbon materials for a wider detection of DA, UA (uric acid), and AA (ascorbic acid). [23,24] The advantages of easy preparing, nontoxic and excellent electrical conductivity of carbonaceous materials, which are rare among energy storage materials, make carbonaceous materials superior to most of the energy storage materials. [25][26][27] There are varieties of approaches for the preparation of carbon materials, such as directly carbonizing from organic precursors, physically or chemically carbonizing from carbon, template methods using zeolites and mesoporous silica, solvothermal and hydrothermal methods with elevated temperature, the electrical arc methods, and chemical vapor decomposition (CVD) methods. [28][29][30][31][32][33][34] Among all these approaches, directly carbonizing from organic precursors is the most frequently used method to prepare nanoporous carbons (NPCs) due to its flexibility and simplicity. [35][36][37] However, these NPC materials present certain drawbacks, such as low surface areas, disordered structures, and ununiformed sizes, which will greatly limit their applications. [25] As studies have progressed, researchers found that carbon materials derived from metalorganic frameworks (MOFs) could overcome these limitations.Metal-organic frameworks, which are also named porous coordination polymers (PCPs), are crystalline porous materials with periodic network structures formed by metal ions (or metal clusters) and organic ligands. [38][39][40][41][42] They are usually prepared by solvothermal methods and used as precursors or templates to form nanostructured materials. [43][44][45] So far, many researchers have highlighted the advantages of MOFs. For Carbon materials derived from metal-organic frameworks (MOFs) have attracted much attention in the field of scientific research in recent years because of their advantages of excellent electron conductivity, high porosity, and diverse applications. Tremendous efforts are devoted to improving their chemical and physical properties, including optimizing the morphology and structure of the carbon materials, compositing them wi...
