Gas Storage and Separation

MOFs are widely eonsidered as promising novel adsorbents for gas storage and separation due to their high surface areas, tunable pore size and structures, and versatile chemical compositions [28,29].

The relevant properties of MOFs have prompted their use for catalysis, gas storage, and separation (Janiak, 2003 Chun et al., 2005 Kaye and Long, 2005 Rowsell and Yaghi, 2006), as well as for fuel cells (Mueller et al., 2006), Li-based batteries (Li et al., 2006 Ferey et al., 2007), and electrocatalysis (Wang et al., 2008). Conversely, MOFs can be synthesized electrochemically, as described by Mueller et al. (2006). MOFs are indirectly related with other electrochemical applications acting as a template for the synthesis of porous carbon to be applied as double-layer electrochemical capacitor (Liu et al., 2008). 

The discovery of carbon nanotubes [1, 2] has led to extensive investigation of adsorption on these remarkable substrates. Much of this effort has been directed toward potential appHcations, such as gas storage and separation, which exploit the fact that every carbon atom of a single-wall carbon nanotube (SWNT) can provide two surfaces, inside and outside of the tube, for... 

Metal-organic frameworks (MOFs), as a new class of porous materials, are well-known for high specific surface areas and high porosity that have potential applications in gas storage and separation, catalysis, sensor, and drug delivery (Furukawa et al., 2010). In recent years, the exploration of MOFs as electrode materials for supercapacitors has also been... 

Boron trifluoride should be handled in the laboratory using the "basic prudent practices" described in Chapter 5.C, supplemented in the case of work with gaseous boron trifluoride with the procedures of Chapter 5.H. All work with boron trifluoride should be conducted in a fume hood to prevent exposure by inhalation, and splash goggles and impermeable gloves should be worn to prevent eye and skin contact. Cylinders of boron trifluoride should be stored in locations appropriate for compressed gas storage and separated from alkali metals, alkaline earth metals, and other incompatible substances. Solutions of boron trifluoride should be stored in tightly sealed containers under an inert atmosphere in secondary containers.

Microporous materials have been proved to have the potential application in gas storage and separation by physical adsorption during last decades [46]. Such application is usually based on the presence of a large permanent surface area, suitable pore size distribution, and suitable enthalpy of adsorption between micropore and gas molecules of porous sorbents. Recent research revealed that microporous materials are considered as potential carbon capture media due to their relatively weak physical interaction with carbon dioxide, which renders the recovery of the gas and recycling of the sorbent less energy...

In conclusion, owing to the high surface area and excellent stability, PAFs show great potential in gas storage and separation, the adsorption of organic pollutants, molecular reorganization, as electrode materials for batteries and... 

In conclusion, as a new generation of porous materials, PAFs are a class of material with intrinsic micropores composed of covalent bonds. Both experiments and theoretical simulation and calculation have shown the potential applications of PAFs in gas storage and separation, the adsorption of organic pollutions and many other fields. Besides, due to their high physicochemical stability and surface area, PAFs are good candidates as host materials that can be loaded with guest molecules or be modified by incorporation of functional groups for specific applications.
