A biomolecule-surfactant co-assembly is developed, allowing for the universal modification of G-O, MXene, and MoS nanosheets. The resulting membranes feature abundant nitrogen/oxygen groups within confined 2D nanochannels. These groups form a hydrogen bond network with the water molecules and undergo protonation inside the channels in acidic conditions, functioning as proton-hopping sites. The increased binding affinity toward salt cations effectively blocks the cations. Notably, exceptional water stability for 400 h in desalination with a 99% NaCl rejection rate is achieved.

氧化石墨烯多功能涂层：用于质子渗透和脱盐的新型膜

开发了一种生物分子-表面活性剂共组装体，可以对 GO、MXene 和 MoS2 纳米片进行通用修饰。所得膜在受限的二维纳米通道内具有丰富的氮/氧基团。这些基团与水分子形成氢键网络，并在酸性条件下在通道内进行质子化，充当质子跳跃位点。对盐阳离子的结合亲和力增加，有效地阻挡了阳离子。值得注意的是，在海水淡化中实现了 400 小时的卓越水稳定性，并且 NaCl 去除率达到 99%。
