摘要：

Capacitive deionization (CDI), as an emerging desalination technique offering an efficient and green route to obtaining clean water, has attracted worldwide attention. Recently, the utilization of the anode or cathode materials of secondary batteries to build hybrid CDI (HCDI) systems has thrived and become a hot topic in the 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) composites were prepared and used as electrode materials 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 the NTP/C composite cathode and AC anode exhibited 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 an electrode material for HCDI applications.
