The efficient adsorption application and electric double-layer capacitor material with low-cost biomass-based activated carbon materials have been quite common recently. In this study, chestnut shell-based activated carbons were produced by chemical activation. ZnCl, HPO, and KOH agents were used for chemical activation. The obtained activated carbon, iodine adsorption from aqueous solutions, and its use as an electro capacitor were investigated. The scanning electron microscope, nitrogen adsorption/desorption, and Fourier transform infrared spectroscopy were used for characterization. The values of surface area and iodine adsorption capacity of the chestnut shell-based activated carbon are 1544 m g and 1525 mg g. As a result, a specific capacitance of 97 Fg with chestnut shell-based activated carbon was obtained in a 1 M KCl electrolyte for the electrochemical double-layer capacitor. This study shows that activated carbon based on the chestnut shell can be used both as an electrochemical energy storage material and as an adsorbent in iodine adsorption.
近年来，具有高效吸附应用的低成本生物质基活性炭材料作为双电层电容器材料已相当普遍。在本研究中，通过化学活化制备了基于栗壳的活性炭。使用ZnCl、HPO和KOH试剂进行化学活化。研究了所得活性炭对水溶液中碘的吸附及其作为电化学电容器的用途。采用扫描电子显微镜、氮吸附/脱附和傅里叶变换红外光谱进行表征。基于栗壳的活性炭的表面积和碘吸附容量分别为1544 m²/g和1525 mg/g。结果，在1 M KCl电解液中，基于栗壳的活性炭用于电化学双层电容器时获得了97 F/g的比电容。本研究表明，基于栗壳的活性炭既可以用作电化学储能材料，也可以用作碘吸附的吸附剂。
