碳纳米管(Carbon Nanotubes, 简称CNT)由于其独特的物理化学性质而得到广泛关注。CNT粉体可通过多种方法制成结构稳定且多孔的三维自支撑滤膜，而如果在此滤膜上施加一定的偏电压，则可实现从传统滤膜(仅能完成污染物的吸附)到电活性滤膜的转变，能够同时完成对污染物的物理吸附和原位电化学氧化降解。因此，这种电化学滤膜技术也被认为是一种新型的水处理技术。
CNT电化学滤膜技术有助于解决由水体中天然有机质吸附、生物膜形成或胶体颗粒沉积等导致的膜污染难题。不同于现有的聚合物膜材料需要定期进行清洗/再生以维持最优渗透通量，电化学滤膜则可以将截留的有机污染物原位电化学氧化降解或将微生物原位灭活来进行“自清洁”。这种电化学滤膜技术快速的传质速率也是其受到关注的重要原因。此外，电化学滤膜技术也可利用有机污染物作为“牺牲”电子供体来产氢以减少对能量的需求。
东华大学刘艳彪团队与丁宁博士和董黎明教授深入合作，在电活性CNT滤膜技术方面开展了一系列合作研究。构建了基于FeOCl修饰CNT阴极滤膜的流通式电芬顿体系（Applied Catalysis B: Environmental, 2020, 260, 118204. IF:16.683），开发了基于聚苯胺修饰CNT阴极滤膜的“一步法”还原-吸附六价铬的流通式体系（Science of the Total Environment, 2019, 695, 133926. IF:6.551），设计了基于纳米零价铁改性CNT阳极滤膜的“一步法”脱毒-吸附去除三价锑的流通式体系（Environmental Engineering Science, 2020, 37, 490. IF:1.61），总结了该技术的研究进展和应用前景（Chinese Chemical Letters, 2020, 31, 2539. IF:4.632; Science of the Total Environment, 2019, 668, 966-978. IF:6.551）。
