Preparation of Metal-Organic Frameworks and Application for CO2 Adsorption and Separation

Metal-organic frameworks (MOFs) is one of research hot topic in material area, has potential to become an important material for CO, adsorption and separation. Three points are introduced, including development and characteristics of MOFs, breakthrough progress of MOFs in CO, adsorption and separation, preparation of MOFs by traditional synthesis and green methods. Mechanism of MOFs for CO, adsorption and some special characteristics and advantages of MOFs compared with traditional adsorption materials are discussed. MOFs modification and improvement methods are introduced. Moreover, adsorption capacity and selectivity of MOFs for single-component CO2, CO2/CH4, CO2/N-2 are given. Conventional MOFs preparation techniques could not satisfy the large-scale production for CO, capture, so mechanical chemical synthesis and wet mineral weathering methods are discussed, which have some distinguishing features, such as greenization, solvent-free, low-energy, simplification and so on. Both of them are valuable for research and potentially practical technologies. With global warming and non-renewable fossil fuels consuming problems becoming more and more serious, studying and developing a series of MOFs materials to meet the requirements of carbon capture and storage(CCS) technology are extremely urgent and still had a lot of work to do.
