Abstract Exploring new carbon‐based electrode materials is quite necessary for enhancing capacitive deionization (CDI). Here, hollow mesoporous carbon spheres (HMCSs)/metal‐organic frameworks (MOFs) derived (NC(M)/HMCSs and NC(M)@HMCSs) are successfully prepared by interface‐coating space‐encapsulating design, respectively. The obtained NC(M)/HMCSs NC(M)@HMCSs possess a hierarchical nanoarchitecture with abundant nitrogen doping, high specific surface area, meso‐/microporous pores. These merits conducive to rapid ion diffusion charge transfer during the adsorption process. Compared NC(M)/HMCSs, exhibit superior electrochemical performance due their better utilization of internal space carbon, forming an interconnected 3D framework. In addition, introduction Ni ions more synergistic effect between ZIF(M)‐derived N‐doped shell compared other (Mn, Co, Cu ions). resultant Ni‐1‐800‐based CDI device exhibits excellent salt capacity (SAC, 37.82 mg g −1 ) good recyclability. This will provide direction MOF nanoparticle‐driven assembly strategy application CDI.

Nitrogen-doped carbons (NCs) have demonstrated notable advantages for application in capacitive deionization (CDI). However, the potential roles of different nitrogen configurations CDI process, especially how neglected oxygen doping synergistically works, remain unclear. In this work, we systematically addressed these critical issues and revealed significant role trace enhancing desalination performance NC electrodes. By introducing into nitrogen-doped carbon nanosheets (ONC-S), using guanine as precursor, obtained abundant pyridinic pyrrolic configurations. This design aims to enhance charge distribution, wettability, ion diffusion target Compared with commercial activated other state-of-the-art materials, our ONC-S electrode demonstrates superior specific capacitance, excellent cycling stability, enhanced efficiency. These findings highlight synergistic effects configuration, offering valuable insights mechanisms driving improved performance. shown applications, but effect Here, study addresses reveals crucial impact
