摘要：

In this work, we report a hybrid material of pyrazine based pi-conjugated organic molecule, hexaazatrinaph-thalene (HATN), and MXene. In this hybrid, MXene serves as a conductive substrate and HATN provides multiple electroactive sites, which are jointly combined to build a unique 3D structure with more ion transport channels for accelerating the charge transfer and ion diffusion rates. The as-obtained HATN/MXene composite displays a superior desalination capacity of 57.5 mg g(-1) with an excellent desalination rate of 13.2 mg g(-1) min(-1) and good long-term stability. This work provides a meaningful guidance for designing and applying organic molecules in capacitive deionization field.
