Abstract Water desalination via capacitive deionization technique (CDI) is deeply affected by the properties of electrode materials. In this work, microporous carbon spheres (CSs) were fabricated by simple green eco-friendly process with low cost materials where glucose is converted to carbon spheres via polymerization reactions through hydrothermal treatment followed by carbonization. X-ray diffraction (XRD), Raman spectroscopy, Fourier transform infrared spectroscopy (FTIR), Field Emission Scanning Electron Microscopy (FESEM) and Nitrogen adsorption-desorption studies have characterized the obtained CSs. Measurements of Cyclic Voltammetry (CV), Galvanostatic Charge and Discharge (GCD), and Potentio-Electrochemical Impedance Spectroscopy (PEIS) were used to investigate the electrochemical behavior. The desalination performance and the effect of different carbonization temperature on the chemical, structural and surface properties were studied. It was found that the CS800 electrode possessed large surface area and high electrosorption capacity (10.3 mg g−1) which suggest its use as a promising candidate for CDI.

葡萄糖衍生微孔碳球电极的环保简便合成，具有增强的水电容去离子性能

摘要 电容去离子技术（CDI）脱盐受电极材料性能的影响很大。在这项工作中，微孔碳球（CSs）是通过简单的绿色环保工艺用低成本材料制造的，其中葡萄糖通过水热处理和碳化的聚合反应转化为碳球。X 射线衍射 (XRD)、拉曼光谱、傅里叶变换红外光谱 (FTIR)、场发射扫描电子显微镜 (FESEM) 和氮吸附-解吸研究表征了获得的 CS。使用循环伏安法 (CV)、恒电流充放电 (GCD) 和电位电化学阻抗谱 (PEIS) 的测量来研究电化学行为。研究了脱盐性能和不同碳化温度对化学、结构和表面性能的影响。结果发现，CS800 电极具有大表面积和高电吸附容量（10.3 mg g-1），这表明其可用作 CDI 的有希望的候选者。
