摘要
工业水回用可有效缓解水资源短缺的困境。但由于水中盐度过高,成为限制其回用的重要原因之一。因此,开展脱盐研究已经成为近年来的研究热点。电吸附方法由于具有脱盐效率高、无二次污染和再生容易的优点,备受人们关注。我们通过耦合有机共价修饰及超分子自组装技术,构建了一种苯二胺功能化石墨烯纳米材料,将其作为电吸附电极开展脱盐研究。研究表明,该电极具有较高的吸附容量,比电容远远高于传统的活性炭电极。组装的电吸附装置在1.6 V电压下,即可快速、高效地去除水中盐离子。
Capacitive deionization(CDI) is an emerging technology that supplies deionized water to resolve the fresh water shortage. Functionalized graphene in particular has recently been regarded as characteristic CDI electrode material. Here, phenylenediamine f G architectures have been constructed successfully, and exhibited the ultrahigh electrosorption capacity. This work provides an effective strategy for the environmental and economical electrode architectures for general applications in CDI and energy storage.
