Selective Separation of Gases by Metal Organic Framework Materials (Mofs)

Abstract

Gas separation is used to separate one or more gases from a mixture, which is crucial in the chemical industry. Compared with conventional porous materials, the distinctive physicochemical traits of MOFs play a dominant role in gas storage and separation. This review focuses on MOF materials in selective gas separation and current challenges. According to research, the usage of porous materials has achieved effective separation and greatly reduced energy consumption in nitrogen/oxygen (N2/O2) separation, acetylene/ethylene (C2H2/C2H4) separation, carbon capture and toxic gas separation. MOF’s unique structural features lead to the promising status for gas storage and separation. However, MOF materials still have some problems and challenges, e.g., the lack of practice for scientists to easily find a high-performance MOFs, high cost of MOF materials and shaping process. In the future, researchers around the world are looking to synthesize more and more artificial MOFs. Overall, these results offer a guideline for improvement of MOF materials.
