Metal-organic frameworks derived NaTi2(PO4)3/carbon composite for efficient hybrid capacitive deionization

Abstract

Capacitive deionization (CDI), as an emerging desalination technique offering an efficient and green route to obtain clean water, has attracted world-wide attention. Recently, utilizing anode or cathode material of secondary battery to build hybrid CDI (HCDI) system has thrived to be a hot topic in CDI field. The HCDI system can effectively solve the problem of low desalination capacity of traditional CDI. In this work, Metal-organic frameworks derived NaTi2(PO4)3/carbon (NTP/C) composite was prepared and used as electrode material for HCDI. The results show that due to the unique porous structure, high specific surface area and good electrical conductivity of NTP/C, the HCDI system with NTP/C composite cathode and AC anode exhibits an excellent desalination performance with a high desalination capacity of 167.4 mg g-1 and good desalination ability. The NTP/C should be a promising candidate as electrode material for HCDI applications.
