Research Progress of Seawater Desalination Based on Capacitive Deionization Technology of Metal-Organic Frameworks
Capacitive deionization(CDI)is an emerging desalination method for removing charged ions dissolved in salt solution in recent years.It has attracted more and more attention due to its advantages of environmental friendliness,simple process,low energy consumption and low cost.The electrode material of CDI is the core of this technology.Metal-organic frameworks(MOFs)is a new type of CDI electrode material with large specific surface area,diverse structure and adjustable pore size.Firstly,CDI and MOFs were briefly introduced.Then,the research progress of seawater desalination based on MOFs material CDI was reviewed.It mainly focuses on four parts:MOFs derived carbon materials and modification,heteroatom doped MOFs derived carbon,MOFs derived carbon composites and MOFs composites.Finally,some shortcomings were put forward,and the future development direction was prospected.
