| 中文摘要: |
| 以椴木为前驱体,二氧化碳为活化剂,制备出具有一定强度、无需粘结剂的电极材料同时用作集流体。利用扫描电镜、X射线衍射仪、拉曼光谱仪和孔径分析仪对材料的形貌和孔结构进行了分析,并使用电吸附脱盐装置测试了其电吸附脱盐性能。结果表明,该材料有大量的微孔结构,比表面积为1440 m2 g-1,电吸附脱盐能力随着溶液浓度的提高而升高,在溶液溶度为200 mg L-1、500 mg L-1、1000 mg L-1和2000 mg L-1时,吸附量分别为2.02 mg g-1、3.76mg g-1、6.21 mg g-1和12.42 mg g-1。 |
| 英文摘要: |
| In this work a novel binder-free electrode material is prepared through carbon dioxide activation by using basswood as a precursor and it is also used as current collector. The morphology, structure, and pore properties are revealed by a variety of characterization methods, such as scanning electron microscopy, X-ray diffraction, Raman spectroscopy, nitrogen adsorption-desorption measurement. The capacitive desalination performance of the material was tested by capacitive desalination device. The results show that the material with a large number of microporous structure possesses specific surface area of 1440 m2 g-1. At the solution solubility of 200 mg L-1, 500 mg L-1, 1000 mg L-1 and 2000 mg L-1, the adsorption capacities were 2.02 mg g-1, 3.76 mg g-1, 6.21 mg g-1 and 12.42 mg g-1, respectively. |
