In this issue of Matter, Zhang et al. developed an electrochemically assisted interfacial growth (EIG) method for fabricating metal-organic framework (MOF) composite membranes. Different from previous works on electrochemically assisted growth of MOF, this work combines a counter-diffusion strategy with electrochemical reaction and realizes a uniform in situ growth of MOF selective layer on a poly(ether sulfone) (PES) polymer substrate. The deposition position of MOF crystals can be easily controlled by adjusting the current density, and the growth of MOF membranes can be well controlled.

制作无缺陷MOF膜的稳健策略

在本期《物质》中，Zhang等人。开发了一种电化学辅助界面生长（EIG）方法来制造金属-有机骨架（MOF）复合膜。与先前关于MOF的电化学辅助生长的工作不同，该工作将反扩散策略与电化学反应相结合，并实现了聚醚砜（PES）聚合物基底上MOF选择层的均匀原位生长。通过调节电流密度可以容易地控制MOF晶体的沉积位置，并且可以很好地控制MOF膜的生长。
