Electrochemical investigation of carbon paper/ZnO nanocomposite electrodes for capacitive anion capturing.

ABSTRACT: In this work, we demonstrate an effective anion capturing in an aqueous medium using a highly porous carbon paper decorated with ZnO nanorods. A sol-gel technique was first employed to form a thin and compact seed layer of ZnO nanoparticles on the dense network of carbon fibers in the carbon paper. Subsequently, ZnO nanorods were successfully grown on the pre-seeded carbon papers using inexpensive chemical bath deposition. The prepared porous electrodes were electrochemically investigated for improved charge storage and stability under long-term operational conditions. The results show effective capacitive deionization with a maximum areal capacitance of 2 mF/cm², an energy consumption of 50 kJ per mole of chlorine ions, and an excellent long-term stability of the fabricated C-Z
