High Performance Capacitive Deionization using Modified ZIF-8 Derived, N-doped Porous Carbon with Improved Conductivity

Abstract

Zeolitic imidazolate framework (ZIF) composite derived carbon, exhibiting large surface area and high micropore volume, is demonstrated to be promising electrode material for capacitive deionization (CDI) application. However, some inherent serious issues (e.g. low electrical conductivity, narrow pore size, relatively low pore volume, etc.) still remain in the nitrogen-doped porous carbon particles, which restrict their CDI performance. In order to solve the above-mentioned problems, herein we prepared gold-nanoparticle-embedded ZIF-8-derived nitrogen doped carbon calcined at 800 C (Au@NC800) and PEDOT doped-NC-800 (NC800-PEDOT). With the notably increased conductivity, the new-generated NC800-PEDOT and Au@NC800 electrode achieve high electrosorption capacities of 16.18 mg/g and 14.31 mg/g, respectively, which is much higher than that of NC800 (8.36 mg/g). The Au@NC800 and NC800-PEDOT should be promisingly applicable as highly efficient CDI electrode materials.
