Abstract

Carbon dioxide emissions seriously harm the environment, causing the attention of all countries. Carbon capture and sequestration is the most direct way to control carbon dioxide emissions in the world. However, CO₂ separation has attracted significant interest due to its high energy efficiency, low operation cost, low investment, and easy maintenance and operation. This article reviews the current main CO₂ separation membrane technologies and summarizes the advantages and disadvantages of various technologies. Sorted by their structures, composite membranes include inorganic membranes, polymeric membranes, Mixed matrix membrane (MMMs) and Metal-Organic frameworks membrane (MOFs). Pure inorganic and organic membranes cannot have both thermal stability and low cost, but MMMs can have both advantages. The problems affecting the development of MMMs are: poor compatibility between filler and polymer, resulting in non-selective defects. According to their advantages and disadvantages, the key issues restricting the development of composite membranes were analyzed and discussed.
