Progress in the Application of MOFs in the Field of Atmospheric Environment

Abstract

Since its first appearance in 1995, metal-organic framework materials (MOFs) have become a research hotspot in the field of environmental treatment due to its advantages of large specific surface area, high porosity and adjustable pore size, especially in the treatment of dye wastewater and heavy metal wastewater. With the deepening of research, as a kind of crystalline material with porous structure, MOFs have a wide application prospect in the field of air purification materials due to their strong adsorption function. This paper summarizes the types and synthesis methods of MOFs, and reviews the application research progress of MOFs in gas separation, gas storage and particulate matter purification. At present, MOFs still have some problems, such as poor stability, low recycling efficiency, high cost and weak functionalization, etc. In the end of this paper, some research suggestions are put forward to solve these problems.
