“…Notably, x Li‐RHA‐MIL‐101 also exhibited hysteresis loop, which decreases with the increase in Li + ion content. Notably, hysteresis loop may appear due to the pseudo‐entrapment of H 2 molecules in the pores or a favorable interaction of H 2 molecule with adsorbent wall . This behavior is also observed in metal hydrides, where a large difference in the adsorption and desorption is observed.…”

Metal-organic frameworks (MOFs) show promising characteristics for hydrogen storagea pplication.I nt his direction, modification of under-utilized large pore cavities of MOFs has been extensively explored as ap romising strategy to further enhancet he hydrogen storage properties of MOFs. Here, we describedasimple methodology to enhance the hydrogen uptake properties of RHA incorporated MIL-101 (RHA-MIL-101,w here RHA is rice husk ash-a waste material) by controlled doping of Li + ions. The hydrogen gas uptake of Li-doped RHA-MIL-101 is significantly higher (up to 72 %) compared to the undoped RHA-MIL-101, where the content of Li + ions dopingg reatly influenced the hydrogen uptake properties. We attributed the observed enhancement in the hydrogen gas uptake of Li-dopedR HA-MIL-101 to the favorableL i + ion-to-H 2 interactions and the cooperative effect of silanol bonds of silica-rich rice-huska sh incorporated in MIL-101.[b] Dr.

“…Interestingly, unlike many other flexible MOFs, in which strong hysteresis always accompanies the stepwise gas adsorption isotherms, the CO 2 adsorption isotherm of RPM3 at room temperature is completely reversible, where no hysteresis is observed. Recently, we completed a more detailed study of CO 2 adsorption on RPM3 46. As shown in Figure a, CO 2 adsorption isotherms were collected over a wide range of temperatures (185, 195, 234, and 273 K).…”

Ligand functionalization in metal-organic frameworks (MOFs) has been studied extensively and has been demonstrated to enhance gas adsorption and induce interesting gas adsorption phenomena. This account summarizes our recent study of three series of MOFs by ligand functionalization, as well as their carbon dioxide adsorption properties. While ligand functionalization does not change the overall structure of the frameworks, it can influence their gas adsorption behavior. In the first two series, we show how ligand functionalization influences the CO2 affinity and adsorption capacity of MOFs. We also show a special case in which subtle changes in ligand functionality alter the CO2 adsorption profile.

“…MOF‐derived carbon materials maintain various advantages originating from their MOFs, such as high porosity (up to 90%), extremely high surface area (almost 10 000 m 2 g −1 ), tunable pore sizes, outstanding cycle lifetime, and so on . As a result, MOF‐derived carbon materials have shown promising applications including adsorption, energy storage and conversion, gas storage and separation, catalysis, chemical sensing, and solid phase extraction . Heretofore, many outstanding explorations have been devoted to improving performance of these applications.…”

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...
