Abstract

The exploration and design of high-performance sodium-ion insertion host materials is of great significance to the development of hybrid capacitive deionization (HCDI). NaTi₂(PO₄)₃, abbreviated as NTP, is famous for its high theoretical sodium-ion storage performance, but due to the poor electrical conductivity, its desalination capacity has been largely limited. Herein we report the design and synthesis of NTP/MXene (NTP/M) nanohybrid by the transformation of Ti₃C₂ MXene under solvothermal conditions. Due to its improved electrical conductivity and enhanced sodium-insertion ability with the introduction of MXene, the NTP/M nanohybrid shows an extraordinary desalination performance including a maximum deionization rate of 29.6 mg g⁻¹ min⁻¹, an ultrahigh desalination capacity of 128.6 mg g⁻¹ and a stable cycling desalination ability, suggesting the promising application for practical HCDI.
