Abstract

Article history: In this work, nitrogen-doped porous hollow carbon spheres (N-PHCS) were well prepared by using Received 10 November 2015 polystyrene (PS) spheres as hard templates and dopamine hydrochloride as carbon and nitrogen Received in revised form 1 February 2016 sources. Field emission scanning electron microscopy (SEM) and transmission electron microscopy Accepted 6 February 2016 (TEM) images demonstrate that the N-PHCS have a uniform, spherical and hollow structure. Nitrogen Available online 9 February 2016 adsorption–desorption analysis shows that the N-PHCS have a high specific area of 512 m /g. X-ray photoelectron spectroscopy result reveals that the nitrogen doping amount is 2.92%. The hollow and Keywords: porous structure and effective nitrogen doping can contribute to large accessible surface area, efficient Carbon ion transport and good conductivity. In the electrochemical tests, we can conclude that the N-PHCS have a Nitrogen doping high specific capacitance value, a good stability and low inner resistance. The N-PHCS electrodes present Electrosorption a high salt adsorption capacity of 12.95 mg/g at a cell voltage of 1.4 V with a flow rate of 40 mL/min in Capacitive deionization a 500 mg/L NaCl aqueous solution. Moreover, the N-PHCS electrodes show high salt adsorption rate and good regeneration performance
