高性能钠离子插入主体材料的探索和设计对混合电容去离子（HCDI）的发展具有重要意义。NaTi 2（PO 4）（3），简称NTP，以其高理论钠离子存储性能而闻名，但由于电导率差，其脱盐能力在很大程度上受到限制。本文报道了在溶剂热条件下通过Ti 3C 2 MXene的转化来设计和合成NTP/MXene（NTP/M）纳米杂化物。由于引入MXene后其电导率和钠插入能力的提高，NTP/M纳米杂化物显示出非凡的脱盐性能，包括29.6 mg g（-1）min（-1）的最大去离子速率，128.6 mg g（-1）的脱盐能力和稳定的循环脱盐能力，表明在实际HCDI中有希望的应用。
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.
