Just for reference, MOF-5 costs $200/kg, MOF-177 costs $130K/kg, and MOF-210 is assumed to be even higher (see Figure 5), comparing to MEA which only costs $2.66/kg (3,4).
What are metal organic framework materials?
Metal-Organic Frameworks (MOFs) are crystalline compounds consisting of rigid organic molecules held together and organized by metal ions or clusters. Special interests in these materials arise from the fact that many are highly porous and can be used for storage of small molecules, for example H2 or CO2.
How do MOFs capture CO2?
MOFs possess several remarkable features ranging from high surface area and porosity to functionality and morphology. MOFs act as an ideal candidate for the CO2 capture process. The main approaches for capturing CO2 are pre-combustion capture, post-combustion capture, and oxy-fuel combustion capture.9 Nov 2020
How many MOFs are there?
Millions of distinct metal-organic frameworks (MOFs) can be made by combining metal nodes and organic linkers. At present, over 90,000 MOFs have been synthesized and over 500,000 predicted.13 Aug 2020
What metals are used in MOFs?
The most common metal ions used in MOFs are Zn(II), Cu(II), Fe(III), and Zr(IV), while terephthalic acid, trimesic acid, or 2-methylimidazole have been excessively used as organic linkers [23].16 Dec 2019
Are MOFs semiconductors?
Upon light excitation MOF-5 behaves as a semiconductor and undergoes charge separation (electrons and holes) decaying in the microsecond time scale. The actual conduction band energy value was estimated to be 0.2 V versus NHE with a band gap of 3.4 eV.
What are MOF materials?
Metal–organic frameworks (MOFs) are a class of compounds consisting of metal ions or clusters coordinated to organic ligands to form one-, two-, or three-dimensional structures. They are a subclass of coordination polymers, with the special feature that they are often porous.
What can MOFs be used for?
Metal-organic frameworks (MOFs) are a class of crystalline materials that consist of coordination bonds between transition-metal cations and multidentate organic linkers. MOFs can be used for gas storage, purification and separation, as well catalysis and sensing applications.
What are MOFs used for?
The structure of MOFs is characterized by an open framework that can be porous (porous materials). MOFs can be used for gas storage, purification and separation, as well catalysis and sensing applications.
How are MOFs made?
MOFs are porous materials made of metal groups linked together with organic molecules—picture the connectors and rods in Tinkertoys. That has generally been done by bathing them in different solvents that have low boiling points for hours or days, exchanging the one solvent for the other in the MOF.18 Oct 2017
