Abstract
具有除菌性能的电容去离子材料对于制备高效节能同时具备脱 盐和抗微生物污染功能的电极材料至关重要, 然而由于双电层电吸附 机制的影响, 多数碳基材料的吸附容量受到限制. 同时, 近年来部分研 究学者通过对电极材料进行抗菌化合物的修饰并用于电容法水除菌已 得到证明. 因此为了实现高效、低成本的同时实现电容脱盐和除菌, 本 研究提出了一种简便的方法制备氧化石墨烯/聚苯胺/普鲁士蓝纳米复 合材料作为类法拉第电极用于电容去离子和水消毒应用. 所合成的电 极材料具有较高的B E T 表面积(148.08 m2 g−1) 、介孔体积 (34.02 cm3 g−1)和孔体积(0.66 cm3 g−1), 在1 A g−1下的脱盐容量为 91.6 mg g−1, 脱盐率为3.05 mg g−1 min−1. 此外, 在未添加额外消毒剂的 情况下, 该复合材料所制备的电极能有效去除和灭活94.0% ± 3.1%的大 肠杆菌, 其杀菌效率是活性炭电极的7倍. 本研究对未来将普鲁士蓝基 复合材料的法拉第电极用于高效环保海水淡化和消毒材料的应用奠定了研究基础.
