| Abstract | ||||
| As a class of versatile porous materials, MOFs have shown enormous potential for adsorption for environmental remediation and fuel purification. To efficiently remove harmful gases, it is not sufficient to use MOFs of the appropriate size/shape of the pores, and other more specific interactions between harmful adsorbents and the host are desirable. Most of the harmful gases are highly reactive. The adsorption of these gases often degrades the porous structures of MOFs. However, much progress has been made in the last few years to develop very persistent organic frameworks. Certainly more and more fundamental studies will appear in this direction, which should enhance the practical application of this type of new porous material for air purification and related fields in the future. MOFs contain multiple functional groups, conjugate bonds, and metal ions that can help for understanding the interactions between MOFs and pollutants and hense increase the adsorption efficiency. MOFs suffering from relatively poor water stability and reuse potential except for some types of MOFs such as MIL, UiO and ZIF are relatively stable in water. The big challenge is converting unstable MOFs in water to stable MOFs; this will lead to high recovery and extend its application. | ||||
