Capacitive deionization (CDI) is a promising desalination technology and its development is highly dependent on the electrode materials. Here, a three-dimensional N-doped porous carbon (3D-NPC) was fabricated for use as a CDI electrode material through the one-step carbonization process with C5H8NO4Na as the carbon and nitrogen source and NaCl as a template. Benefiting from high-level N doping (4.93 at %) and a high surface area of 1481 m2 g−1 with an interconnected hierarchical porous structure propitious to the ion and electron transportation, the 3D-NPC exhibited an excellent desalination capacity in CDI. It was also very ...

It was also very impressive that 3D-NPC was used as an electrode material for a Zn-air battery, displaying outstanding catalytic performance with an open-circuit voltage of 1.34 V. Furthermore, the Zn−air battery can drive the operation of a CDI device, showing a high salt adsorption capacity of 19.4 mg g−1 and good applicable stability. The findings in this work will pave a way to develop energy-integrated capacitive deionization technology.
